Anyone know if an M&P 2.0 Compact 10mm is in the works?

Thanks

A 4" version already exists, how much more compact are you thinking?

I can tell you from experience that really short firearms chambered in 10MM Auto have a heck of a bark when firing full power ammunition

My CS10s are my two most compact pistols in that caliber

You could always buy a springfield-xd-m-elite-3.8-compact as it is as small as you can hope to see .

Might as well just get a 40s&w as it will be the same difference

Just wanted something slightly smaller, to the exact size of the 9mm compact.

A 4" version with full size frame already exists in 9mm aswell but they still made a compact frame.

I just did exactly that yesterday...a 40 cal 3.1" Shield 2.0. Then I ordered a drop-in conversion barrel for it so I can also shoot .357 SIG rounds. Life will be good when my purchases are in-house.

Sounds good. What Repr650 and others who jumped on the 10mm bandwagon do not realize is that the ballistics on these 4.5 or less handguns with commercial 10mm is almost identical if not identical to 40s&w. They have the false misconception that they're carrying something so much more powerful when all they're really doing is carrying a bigger and more expensive handgun with more expensive ammo.

10mm is the new fad and current flavor of the month though. Even though 10mm self-defense
rounds are not doing anything better than 40s&w in these small carry sized handguns, many gun owners have been groomed to be anti 40s&w and pro 10mm by gun magazines and firearm manufacturers.

Incorrect

What changes is that the muzzle velocity difference narrows as the barrels of the two firearms get shorter

However, a Faster Cartridge is ALWAYS FASTER than it's slower brother when fired from the same barrel length and style of firearm no matter what that barrel length is

The two cartridges NEVER ARE EQUAL when fired from the same barrel length and style of firearm

It is up to the individual to decide if the velocity gain is worth it to him/her

BTW, I jumped on the 10MM Auto Bandwagon in 1984 and have been shooting it and developing ammunition for it ever since.

They are just about equal in performance wise and when it comes to diminishing returns for self-defense against humans. They just are.

FYI, you can also have two 10mms by different manufacturers or even two 9mms by different manufacturers of the same weight but different velocities. Even still, both will perform similarly. Yes, 10mm rounds may have a little faster velocity, but they aren't really over performing 40s&w. What you get is maybe, for example, 20" of penetration instead of 19 with simular expansion in many cases.

I can't speak on any reload ammo you say you personally developed, but I can speak on what's sold commercially. I assume you have access to ballistic gel? Can you setup and video your results out of a sub 4.5" barrel so I can compare it to other 40s&w offerings?

In your original post you said "if not identical to 40s&w"

Now you are walking it back to "just about equal"

"just about equal" is not EQUAL

It is just common sense that two loadings from different Manufacturers will always Perform Differently . . . . So What

A 10MM Auto loading in a firearm that has a 6" barrel that clocks faster than a similar weight 40S&W loading in the same style of Firearm with the same length of barrel will ALWAYS BE FASTER than those same two loadings when both are clocked from a 4 1/2" barrel in the same style of Firearms

The claim that Is Totally Incorrect



You can not ignore Physics and the science of Internal Ballistics just because you want to

I have not brought up any reloads in my previous posts.

The 10MM Auto ammunition that I developed was for Commercial Sale to the US Government for their integrally suppressed 10MM Auto SMGs that were intended to replace the aging inventory of MP5/10s

Of course we make blocks of 10% ballistic GEL for wound channel studies

If you want to learn, you need to do the work yourself

I am not walking anything back. I know you're a fanboy thus your blood pressure is up, but maybe you should go back and read what I said again. What I said is and I quote: "almost identical if not identical." "almost identical" and "just about equal" is the same thing buddy. Calm down and read what I actually stated. I'll accept my apology now please.

Next, there are 10mm offerings that are simular velocities as 40s&w offerings hence my "if not identical" comment that got you all riled up.


So what? I explained that in the rest of my paragraph. Stop taking out a snippet, quoting it, and then pretending to not get the point.

My point is you brought up "speed" aka velocity. My point was velocity is not the be all. Velocity is not the only factor that dictates performance down range. You can have a 10mm round with higher velocity that will still perform similarly in ballistic gel and other testing than 10mm round that is going slower or faster. Likewise, a slightly faster 10mm round doesn't automatically translate into better performance.


I don't know anything about 6" barrels or have any data on 6" vs 4.5" barrels with regards to 10mm and 40s&w which is why I didn't mention anything longer than 4.5". I did assume that a the longer the 10mm barrel the bigger the difference in velocity would be. That is, the velocity difference between a 180gr 10mm and 40s&w (if any) out of a 3" barrel will be less pronounced vs out of a 6" barrel.

I don't need to learn anything. You referenced 10mm you claimed to have developed, and I simply asked for a ballistics gel video. What is the name of this 10mm ammo you developed, so I can look up the data and compare.

All true for certain!

I'll stick to .38 Special and 9mm, maybe occasionally .45 ACP. I don't expect to be confronted by Arnold the Terminator.....

Obviously, YMMV is most applicable here........

Come and take it!!

The 9mm compact is a shorter grip than the Full Size but 2 rounds less in the compact too and the barrel on the full size is 4.25 not 4" . Small details but get'um right !

I carry a 4.25 or 5" 2.0 pc 40 with underwoods 155gr hp will average 1318fps . The 5" 1338fps . 165gr hp will do a little over 1200fps Not sure for many whats so special about a 10mm if CC is a concern but its not really hard to find what choices you have .

If you purchased ammo for self-defense to EDC in say, for example, an XDM 3.8" 10mm, what would you choose?

Dude, not sure why you're being so argumentative but there are plenty of full power 10mm offerings available that aren't even in the same universe as 40 S&W. Underwood, Buffalo Bore, pick your poison. No gel test needed.

People have been saying 10mm was a "bandwagon" and a "fad" for over 30 years but yet there are more and more of them being produced now than ever before and with a multitude of full power ammo offerings.

10mm is best mm.

It is the new fad. Yes, 10mm has been around for a while, and the minority of people have been carrying and shooting it for years. I agree with you there. With that said, there's no doubt that out the blue all of a sudden within the last few years 10mm has become the new fad that everyone wants to get into even people who had no interest in the past until they seen everyone else doing it.

A couple of Buffalo Bore and Underwood self-defense offerings are NOT a lot or "plenty." Most are FMJ or flat nose hunting rounds that 99.99% of people aren’t going to carry for self-defense nor will they kill anyone deader vs using 40s&w. People like to tout heavy FMJ or FN Buffalo Bore and Underwood hunting loads that they aren't going to EDC when they make an argument for 10mm, but then put some other more realistic 10mm JHP in their 4" polymer pistols that's basically a 40s&w.

Your 180gr 10mm Underwood XTP isn't doing anything that 180gr 40s&w can't do other than maybe over penetrate .5" or so further.

What penetration and expansion are you getting with your 180gr 10mm Underwood XTP? I want to hear what you're getting based on your own experience or what you seen.

Not a m&p but one more choice below for you but remember , short barrels and hot loads may not be reliable !!

Just a moment...

So many think the 10mm is all that . Guess they never seen or fired a 40 super over a chrony !! 220gr bullet at 1350 fps is move'n right along for a pistol . Children ,, I mean adults and there - My toys better than your toy mentality .

A year ago, I purchased a Compact 2.0 45 acp 4" barreled pistol and an M&P 2.0 (full size) 10mm 4" barreled pistol. Those two pistols share virtually identical dimensions - and each fits, with equal snugness, in my owb holsters.

So - to the OP, while S&W's nomenclature used to describe those two pistols differs (one is called full size, the other is called compact), I view them as functionally being virtually identical (save the calibre of course).

Not much support for that caliber these days.

With the resurgence of 10mm it would be cool it it came back also, but not holding my breath.

Its not like I care as Ammo is available for the 40 super those that don't reload and barrels are available for a number of handguns for the guys that just got have a cartridge to brag about !! Silly boys and there toys .

Just stated that the 10mm is not all that , and mentioning the 40 super ammo can still be just one more choice for some braggers . Just remember if the brain or spine are not turned off with one shot no typical handgun cartridge is all that .

I think most who live in the real world, especially those who have first hand experience realize this.

There are always going to be gun owners who like to have a cartridge that they can brag about and there's nothing you, I or anyone else can do about it so there's no point in getting emotional. Does it make them a bad person.

I like 10mm but I know what it is and what it isn't.

One thing I like to do the day before a USPSA match is to shoot my 10mm because it will make my 9mm feel like a 22. It's like when you're on deck practice swinging your weighted bat.

Exactly... 10mm isn't moving fast enough for to cause damage like a high power rifle round would. All 10mm does is poke holes just like other calibers. The extra energy simply allows some 10mm rounds to have enough energy to poke deeper holes. That may may a different with a big 4 legged creature with thick fur, muscle, fat, and bone thus allowing the bullet to better reach vitals, for self-defense against humans, it's pointless IMHO. I've seen simular grain JHP bullets in 40s&w and 40s&w darn near expand to simular diameters, but the only difference is that 40s&w may have gone 18"-19.5" and the 10mm an inch or and inch and a half further. Both rounds not hitting vitals aren't going to stop an attacker unless they choose to. Both rounds hitting vitals will shot a threat. Those who think 10mm is going to necessarily give them the "one shot stop" or kill someone deader just because it has more energy/velocity to travel a little further (often over penetrating), and just fooling themselves.

Also, the 10mm JHP that's typically sold is designed to somewhat fit into the FBI standards most expect from their JHP self defense rounds. It's usually under powered, yet those who typically carry the ammo will pontificate about how much more powerful their 10mm is while craving on 40s&w when they both perform similarly with similar expansion within FBI specs. Yes, you might get more velocity out of the 10mm, but both 10mm and 40s&w will be engineered to be within FBI specs regardless. I don't care how much velocity you get, but rather how is the round performance down range vs other rounds and how does that translate to giving you an edge in a self-defense scenario.

You can't tell these people anything because they usually become defensive and start talking about velocity, velocity, velocity and will ignore everything else. They think that because their slow handgun round (in relation to rifle rounds) has more velocity that they're doing so much more damage. They're still just poking holes. There's just diminishing returns with using 10mm for self-defense against humans and even many animals.

If someone feels more confident with a faster bullet or whatever I could care less.

Some people here and all over the internet get too emotional over these subjects on both sides. Same thing happens with red dots on pistols.

Too many Chiefs and not enough Indians in the firearms community. Most think they're John Wick and Jordan Peterson all rolled into one.

What it does is give you in between .357 and .41 Magnum (neither of which are barn burners) performance in a semi-auto pistol. It is capable of significant ballistic performance improvement over the .40 S&W, analogous to the .357 over the .38 Special. It is an adequate chambering for a pistol carried when hiking in bear country. For home defense I like a .45 Auto. For concealed carry I like 9mm. I see no use for a compact pistol in 10mm. You lose the ballistic advantage and gain recoil in return. Not a good trade IMO.

I did a little pruning...

Please take a deep breath and note the following (from our rules):
