m&p 9L ported core

[Raiderse]

Hi folks, I am new to this or any other forum. I am hoping to pick your brains a bit. I recently purchased an m&p 9L ported core and I can't hit squat with it. It seems to have excessive play in the barrel and slide. Does anyone have one with similar issues?

Send it back to S&W I just went through this with my 9mm 5" Pro. Barrel and Slide and front sight was replaced. Shoots good now.

I can't help myself. I have to add this: I have NEVER seen so many people discuss the reasons for inaccuracy of a firearm as I have since joining this forum. Changing sight height ,barrels, testing, firing experimenting, changing sights, trigger kits, blaming people for how they shoot... if you bought a new firearm you should be able to just shoot it! From My experience. Some may have good accurate pistols some may not. Some may just try to defend them for whatever reason. I personally saw real problems with the M&P that I never saw with any other brand I own. ... i.e.. Walther, Beretta and CZ , Striker or hammer fire. I have also shot SIG, and Glock, Nothing was like hurling rocks like the M&P. There is a REAL PROBLEM with these M&Ps, In the area I live there are MANY for sale used. All Models, .45 9mm .40 Full size Compact, etc. Dealers Don't want them, and dealers and Gunsmiths alike don't have much good to say about them . No matter if they sell them or not. Its a decent design, just not well executed and I'm sure the ones used by their shooting team and on TV are specially made and tested as are the ones sent out for review. They can send the customer any freebees they want to. it doesn't make up for the failure of the firearm to deliver. As someone that got burned... What we are seeing here is a Company that is spitting out firearms "haphazardly" and skipping quality control to meet the demands and cash in on the rush on gun purchases. If a person wants a project gun. Go buy someone elses problem for $200 and experiment. We buy these new. and higher end models thinking we are buying a well made firearm. As far as them correcting the problems with production updates... Mine was manufactured in March of 2016

JUST MY OPINION

Hi Every one! I am in Australia! Just picked up my ported core yesterday!
first time to own a pistol,I just started shooting IPSC. I am X grunt so not new to shooting.
My pistol shoots very low and slightly to the left,and iam not talking new shooter low and left! its really low!
I shot it yesterday first time,also got a couple of our clubs top shooters to try also very low slightly left!
Please recomend replacement sights shooting IPSC?
also the front sight fouls up from the ported barrel couldn't see the white dot at all after 6 to 10 mags!
I am also considering an Apexp trigger kit any recommendations?
Also mag springs very tight hard to put rounds in??
Thanks Martin

Dawson Precision is the way to go but I'm not sure about availability down under.

It's very common for experienced shooters to shoot low and left when they aren't used to a M&P specifically, they have a different grip configuration than other pistols. Give it some time (and practice)

No recommendations, I shoot open.

Depends on which division you're going to shoot in, there are restrictions in certain divisions. (I shoot USPSA, so I'm not up on IPSC rules)

Also mag springs very tight hard to put rounds in??

How many rounds in your mag (what's legal in OZ these days?) S&W has this weird policy of putting the same mag spring in all sizes of mags. 17/15/10 round Full size and 12/10 round Compact mags all use the exact same spring (what's with that) The springs work fine on the 17, but are tight to impossible on the others. I cut loops off the springs for shorter mags to make them easier/possible to load. Just be careful if you have restricted mags that you don't make it possible to load one more than is legal. From what I hear, the government down there doesn't have much of a sense of humor.

Thanks Martin

Enjoy your foray into competition, it's a lot of fun.

UpLula magazine loader is the cure

Yes fouling front sight! My main issue with porting, I wish I had done the research on ported barrels before I purchased it, I would have gone with the non-ported. I suppose a non ported barrel replacement, Of course have no Idea which aftermarket non-ported to drop in the 9L PC ported.

Video was Excellent, but focused on barrel performance only. There are too many other variables in the accuracy issue. The Apex man mentioned twice that the true benchmark are finely tuned 1911s. If you really want accuracy, dump the polymer gun and get a good 1911 and practice, practice, practice! Regards, Ed

What grain bullet are you using? Try different grain bullets. I might be that yours does not like 115 grain bullets, that it loves 124 or 147. When my daughter bought her CZ One of the things she had done was having FO sights put on. We shoot 124 grain bullets. The original FO sights that were put on where shooting low by multiple inches. They had to put a different height front sight on so it shot true with 124 grain bullets. So my suggestion is to try different grain bullets, you might be surprised.

As to the Apex kit... are you going to go for carry optics class? If no, then I recommend the FSS kit. The FSS kit is in both my 5" Pros and the husband's Core. On my ported core, I am keeping my options open. I already had an Apex competition spring kit and an Apex competition kit that I took out of another gun. From those parts I replaced the trigger return spring, the sear and sear spring and the striker spring (not really needed). It is running great at 3 lbs and I still have the original physical trigger. So with a barrel swap (I also have an Apex barrel) I can shoot in carry optics if I want.

As to the front sight dot disappearing due to crud being ejected from the ports... I think that is just the nature of the beast.

Guys complaining about the front sight fouling up must be shooting some real dirty ammo. I shot 150 rounds on Saturday and the white dot was still perfectly visible. I'm currently using W231 in my 9mm reloads and it burns super clean. Entire gun was cleaned in a few short minutes using LPS.

Perhaps try a different brand of ammo or switch powders.

Maybe some people shoot more.

Claims to have shot 6 - 10 mags. If they were 17 round mags then he shot between 102 & 170 rounds.

So in this particular case if I had shot an extra 20 rounds to match his 170, the dot still would have been visible.

I can't imagine that putting it on a rest scatters the shots so widely because if it's off, it should be consistently off in one spot. No offense OP, but have the range master shoot it and see what the range master's results are.
