Anyone want to share some love for the M&P 1.0?

Update: I ran into a little snafu when doing the trigger job. Turns out my particular M&P1.0 is pre 2011. Prior to Sept.2010 M&P used a very small, 1/16" diameter sear spring and plunger, as apposed to the larger 1/8" spring and plunger used in later units.

So, I could not install the reduced weight sear spring that came with the M*Carbo kit. I did install all the other springs and polished all the internal parts as shown in M*Carbos excellent tutorial video. I also installed the Apex polymer trigger.

The trigger has made a big improvement in pre and over-travel and most of the grittyness is gone. The pull weight seems only marginally lighter right now. I think this is mainly due to not being able to use the reduced weight sear spring.

I have ordered a complete replacement sear block assembly that has a larger sear spring hole, spring and plunger so that I can utilize the M*Carbo sear spring. I'm hoping this will reduce the trigger pull weight and take the last bit of crunchiness out of the trigger.

Stay tuned.

Had to do that with my first M&P 9mm, I believe I picked that up at Brownells.
 
Update #2: New sear block assembly came in. I replaced the plunger spring with the lighter one from M*Carbo and polished the sear with Flitz before reassembling and installing it in the gun.

The verdict: Mixed. I don't have a pull gauge so I can't give specific numbers but the trigger definitely feels lighter than it did before the modifications. It is also much smoother, all of the grittiness is gone now. There is still a fair amount of take up, but it's not as noticeable now that the grittiness is gone. Overtravel seems to have been nearly eliminated. The trigger reset point is still a mystery with no tactile or audible clues to alert me where it takes place.

I only completed the work yesterday morning. Family obligations the rest of the day and wet weather today has kept me from sending any lead down range with it yet. I'm looking forward to getting to the range and seeing how the modifications affect my scores on the 6" and 8" gongs. I'm also curious to see if the rock solid reliability has been affected any.

In the end it's still a service grade pistol, now with a pretty nice trigger. I would say that the cost of the Apex trigger and M*Carbo spring kit was well worth the time and cost. However, the unexpected added cost of the newer style sear block, necessary to upgrade the springs, was a bit of a bummer. I think the results will fit my intended use as a range toy and home defense weapon. If I were more serious about competing with it I would have spent the extra dough on a full Apex RAM kit.
 
I have a 40S&W v1.0. Also have 9mm and 357 sig barrels. Apex duty action kit installed and will install a flat trigger after the holidays. Also want a fiber optic front sight. This M&P has been flawless after 2-3 thousand rounds. I also have a shield 1.0 and plan to do similar trigger upgrades. Lots of love for these 2 guns!!
 
In 2012 I was looking to buy a Shield 9mm but they were not available. The M&P 357c was. My 357SIG came as a Range Kit with S&W Trijicon night sights, three 10 round magazines and a hard case.
I've acquired two 15 round magazines for longer shooting sessions.
To totally round out this pistol package I have a S&W .40 S&W barrel and a S&W 9mm barrel with three 12 round and two 17 round magazines. Love the gun.
I have other pistols so this one only have about 300 rounds through it. Just broke in.
I joined this forum right afterward.

I've got a M&P Pro that has been a great pistol, accurate, reliable, and fits my hand really well. I did drop in an Apex trigger shortly after I bought it. She's a keeper! :)

What's been your experience with the Apex trigger? Do you feel there was a big difference between it and the stock trigger? Did you de-burr and polish mating surfaces in the fire control group when you installed the Apex trigger? Is your reset point tactile or audible?
 
I have a full size M&P 1.0 .45 ACP that I bought new for a great price at the local shop. Clerk ordered a large number of them by mistake so store put them on sale. Great gun. Ten rounds .45, points like a Hi-Power, 1911 type Manual Safety, rail.
+p .45 ACP 230 gr. hollow points of every brand/type that I have found , No Problems.
Not really concealable. It needs a duty holster and that's how I carry it in the woods and range.
I haven't seen many compact M&P's around until this past year. I would have grabbed a .40/.357 Sig without a doubt if they still made the .357.
 
I have an original......

...Shield 9mm, so I suppose it is a 1.0. How do I like it? It's GREAT! What modifications have I made? None, except painting the stupid dots back on the sights when they popped off after a few months of shooting.

I've still got it and don't plan to get rid of it. However, I did get a Shield 9mm and .380 EZ for my wife. She ended up liking the .380 EZ so I'm sitting the 9mm EZ at this moment.

I have a performance center V1.0 with a Apex short reset trigger. While the trigger break isn't that much different than what the PC sear provides the reset is much shorter ~ 1/8" or less. The reset is both tactile and audible but neither is strong or loud. I changed it cause I dislike the whole hinged style trigger but if I were to do it again I might have just changed the trigger itself. I do like the short reset though. Interestingly the trigger ended up weighing in at 1 pound 12 oz.

Have the Gen 1 Three Bears, full size, 9c, and Shield. Aside from having the gunsmith smooth out the much maligned factory triggers on the Compact and Shield, they're out of the box stock. They all run like scared rabbits and I'm good with all three. Nice as the Gen 2's might be, what I have do just fine.
 
The beginning of 2016 I bought a Storm Lake .357 Sig barrel. Based on what I had read on forums, it was a simple drop in conversion just as expected.The Sig was great; I find I had tighter groups than with the 40 and the recoil wasn't much more than before.

A few months later I made another change, a first for me. I took the handgun apart and installed the Apex kit and RAM.

In 2018 I bought a Storm Lake 9mm conversion barrel that was on sale, I now had all three calibers to work with on my compact. The nice thing was, the sights and trigger were what I was used to and had been broken in. And like others have said, it makes it easy to change and compare the performance and handling of each cartridge.

Because Connecticut is a restricted state I could only have ten round mags so I carried the compact as a 357 Sig to have more effective rounds but did most of my range time with 40 or 9mm.

In late 2019 Walmart decided to abruptly and without any publicity liquidate their pistol ammo at fire sale prices. I had the chance to hit two Walmart stores in my area that night after my shift and buy up all the 40 S&W they had - the 9mm and 357 Sig were already gone. I had never bought so much ammo before but the price was just too good to pass up.

Then 2020 happened. One of the few things I could still do when everything shut down was go to my rod and gun club and use the ranges. I was going once or twice a week, and I never had to worry about running out of ammo - 40 caliber that is. If I only had a 9, or God forbid, 357, I would have been screwed. As it is, I still have some of that 40 on hand!

At the end of 2020 I moved to Florida and could finally have mags of more than 10 rounds. I bought an Apex threaded barrel and sent the slide to DP Custom Works to have it milled for an RMR. I now have a red dot and 12 rounds of 9mm, if I want I can carry a bigger mag with the sleeve.

I recommend getting a 40 S&W handgun and then a 9mm barrel and maybe even a 357 Sig barrel. You can try the different cartridges and you have options should 9mm become scarce or expensive.

I bought a Detroit PD .40 with case, backstraps, and 3 magazines for $310 about 5 years ago. It had a slightly heavy trigger pull but for a gun with no manual safety I wouldn't want it much lighter and the trigger was probably ideal for the average police issue cop gun. I really thought the gun was about perfect till I tried the 2.0 but the 1.0 is still a great gun and I personally like the .40 better than the 9mm for defense and the M&P seems like a perfect platform for it.
 
90k through my M&P 40 1.0. For many years I swapped in a 9mm barrel and mag to shoot 9mm through it.
I later got a used 9mm slide for $150 and a couple of years ago I got a new complete frame for $99.
Now I have a complete M&P 40 and M&P 9.
Both have the Apex FSS kit but I kept the original hinged trigger which I prefer.

I have no desire to go to a 2.0 9 or 40 unless I kaboom one of them. These things last forever.

I'm a known HK fanboy...but I'm thinking about buying one of these and doing what WireguidedMarine mentioned above.

The reliability of the original M&P that rsrocket1 mentioned and the ambidextrous slide release are appealing to me.
 
My first M&P was around 2007 or 2008... I heard the range staff on my department was testing them so I bought one. It had some reliability issues and I ended up selling it. Fast forward to early 2011 and I bought an M&P9C for backup and off duty use. I actually carried it as a backup a bit but mostly off duty. Later in the year my previously broken trigger finger started to not work so good and after a time I couldn't pull a DA trigger very well. I purchased an M&P9 and avoided going light duty again.

I didn't say anything about my trigger finger because I was in the process to potentially be promoted to a full-time firearm instructor with the Weapons Training Unit. That ultimately happened in October of 2011. At the time they didn't have instructor pistols (the M&P was, at that point, our issued pistol to recruits in the academy) so I continued to use my personal M&P. During the ~ two months between mid October and Mid December I tracked how much I shot and it was over 15,000 rounds through my M&P... Since I wasn't "on the street" any more, I thought it would be a good experiment to not clean or lubricate the pistol to see how long it lasted. It lasted the whole time with no issues.

In December we were issued instructor guns. I used that pistol for a year (trigger finger got fixed in the meantime) before it was switched out for the "new" 1.0 guns we were getting for the department conversion. I also turned in my issued Beretta 92FS to be issued an M&P as my official duty gun. I bought the Beretta six months or so later once the department was set up to sell them back to us.

A year or so later I ordered and received two M&P9Ls and used them for a long time... but eventually moved away from the M&P platform... sorta.

In 2017 there was controversy and a push to move away from the M&P. I don't know the motives but I felt it was not based on what was best for deputies or the department. As part of my frustration I embarked on a torture test of my instructor gun. It had already gone several years without being cleaned or lubricated... several years and around 30,000+ rounds.

I threw it in a creek. I buried it in sand. Ground it in mud. Started spraying it with salt water every day. Threw it in a deep mudpile. Had a class of recruits shoot a full magazine as fast as they could - one after the other - for around 350 rounds... the gun started to melt the plastic chair when set down towards the end. By the time I was done the original recoil spring had broken a coil (around 35,000 rounds) and I put in a new recoild spring assembly. The pistol had over 40,000 rounds and had only choked when I poured really fine sand directly into the gap between the slide and frame. funny thing was I put a drop of Lucas oil on each frame rail, on the barrel hood, and on the trigger bar tail... and it started running again. That was probably around 37,000 rounds.

I'll admit... the M&P 9mm 1.0 pistols weren't the most accurate, and I wasn't super happy with the bump-loading, but they were frigin' tanks!

Then the department moved towards the 2.0 to "fix" things I didn't think were broken about the 1.0. I was so mad I avoided the 2.0 entirely for the testing process (I recused myself since I was already biased against the whole thing) and refused to shoot a 2.0 for almost a year. When I did it was a pretty big shock... these guns were FANTASTIC! I ended up buying several and then we moved toward optics so I picked up several 2.0s with optic capability and a 1.0 frame to mate to a Simunitions slide assembly for Force-on-Force training. My last M&P purchase before I retired in September was a 5" 2.0 Pro Optic Ready and it is awesome.

All in all, before today - and if my recollection is correct - I've owned 18 M&Ps, all in 9mm, and a 9mm Shield.

Today my wife and I went to a local pawn shop here in East Tennessee and there was what appeared to be an almost NIB .40S&W M&P 1.0 Pro C.O.R.E. for less than $400, which is about as cheap as I've seen around here. I've been really thinking about picking up a .40 as a field/woods gun that can easily transition to a carry gun - I have some .40 ammo since I have a Para Ordnance P-16, but It's not really my idea of a woods gun.

Anyway, it came home and now hosts a Holosun 507C and a Streamlight TLR-7. I may change the light as I think about how I'm going to use it, but I have a decent amount of Remington Golden Sabre, Federal HST, Winchester Ranger-T, Some Speer Gold Dot and G2, and a couple boutique ammo manufacturers, and a few hundred rounds of FMJ to make sure it runs with whatever I decide is going to be the carry load. I'll probably pick up some dedicated animal defense loads too to try.

Lastly, and after reviewing posts above... I'll be in the hunt for a .357Sig barrel... I really like that caliber!

Wow! Great story.That is really a testament to the reliability of the 1.0. I have a .40 1.0 however I haven't shot it much since the Shield has pretty much taken over EDC duties since my retirement. This thread reminds me that I need to pick up a .40-9 conversion barrel and a .357 Sig barrel for a three in one.
 
That was a really great testimonial, SoCalDep!

The 357 SIG barrel suggestion from AppStFan is a truly GREAT one: just remember to double check magazines and bullets EVERY time, please!;)

Cheers!

P.S. Getting a SS 357 SIG barrel makes it pretty easy to distinguish what's what...

P.P.S. ApStFan: as a MIAMI of OHIO grad, congrats on the ApSt victory in what had to be the WETEST bowl game in recent memory!:eek:

Update #3: I really need to retire so that I have more time to enjoy my hobbies.

Finally got a chance to throw some lead down range after doing the trigger mods. and I have to say that I am in love with my M&P 1.0 all over again. Slapping the dueling tree paddles back and forth with the 9mm barrel installed was ridiculously easy. The trigger is very crisp and lite now, and I much prefer the feel of the solid Apex trigger to the OEM hinged trigger. Wish I had made the modifications years ago.

As a side note, I also got to try out a S&W M22a .22lr target pistol that I had just picked up at a local gun & pawn shop this past Monday. It too has an awesome trigger, coming very close to the Volsquaerten trigger I put in my Ruger MkII Target pistol.

Still hanging out in my night stand beside the bed. Always shoots good!

I absolutely love the M&P 1.0 Series.

To date, I've scored two excellent deals on 1.0s which provided me with excellent pistols at extremely affordable prices.

The first was back in January of 2021, when I was shopping for a new lightweight concealed carry pistol for Summer. I found a brand new Performance Center M&P40 1.0 for just $369. I was honestly so shocked that at first I thought it was too good to be true, but then I realized that it was a .40 S&W and folks were being extremely snobbish towards the cartridge at the time.

I've been carrying it in Summer ever since and absolutely love it.

Back in June this year I found another great deal on a police trade-in M&P40c, like new with 3 magazines and Trijicon night sights for $269!

It's similar in size to the Shield, but with a slightly shorter grip and a more width because it's double-stack.

Needless to say, it also quickly became part of my carry rotation, replacing my Sigma SW40VE.

I feel that the Smith & Wesson Sigma Series is also worthy of honorable mention, seeing as I got mine like new in 2019 for a mere $199, and while it has been retired, it still sits beside me as I type. It's perfectly reliable, but the trigger leaves a lot to be desired. M&Ps are much nicer in that regard.

I shot and carried my M&P Shield 9 a little more this summer. It fits my hand better than my Glock 26. I'll be tacking a few handguns to Florida for the winter. The Shield 9 will be my main belt gun with a J-Frame in my pocket.

Congrats on the 22A, they are amazing! If you take it down to clean it, you'll notice a small plastic spacer on the back of the recoil rod. You can find them online, but most everyone wants an arm and a leg for them. You'll want some spares, so give S&W a call and tell them you'd like to buy some if they have any available. They will gladly refuse to sell you any but will offer to send you a few free grata if they still have some. The part number for those Recoil Spacers is 315560000. For a little fun at the range, shoot some CCI Vipers through it. The fire ball coming from a .22 will draw some attention.

Thanks for the heads up on the spacer. I will be calling S&W's CS dept. right after the first of the year. The one in my gun appears to still be in good shape, but not having a new unused one to compare it to I can't be sure.
 
Shield 1.0. Heavy trigger but served me well.
