OK, so grabbed another M&P the other day. Shot it today, and had a jam every 3-4 rounds. 3 types of ammo, and both mags. I even limp wristed it a few shots, didn't seem to affect it. After about 75 rounds, it settled in and ran fine. But in my mind, I need to know what caused the gun to jam up. Any ideas.

M&Ps have been having a problem firing out out battery. Smith & Wesson won’t own up to it. Instead they said it could be .250” out of battery and still be safe.

First two photos look like a magazine spring that is too weak or a follower that is hanging up. Last one looks like limp wristing.

I disagree that a new non competition style pistol should need to be “broken in”. Yes, the trigger and action should smooth out, and I’d be willing to forgive maybe ONE non-ammo related issue in the first 100 rounds, but that’s about it.

Also just realized if the slide is dragging on something during recoil, it could cause both problems.

A friend of mine has a S&W that did that. Sent it in and “no problem found”. He sold it at a gun show. There was a thread about it at the old place. He won’t touch a S&W anymore. I have one M&P and love it, but keep it in the back of my mind that it’ll fail.
 
I said it back at the other place. I have an M&P 9mm compact I got on a screaming deal from PSA years ago, like $225 I think. Shot it a few boxes and I feel like I was ripped off .

What an unmitigated peice of garbage.

Fire control system still functional (till it don't).
Sent pics and swarf off to "nobody cares@ glock.cum" and crickets.

So a brandy new weapon should have this from the factory?PLUS THE SHITTTTY TRIGGER?:flipoff2:
Ftf is unacceptable for the average joe!

I will tear it down and see what I find then run it a bit more this weekend. Just seemed odd how it was jamming up on the rounds out of both mags like that. Hadn't seen that before.

Is it rain on the top rear slide or is it slinging lube?
Just a longshot...
Stranger things have happened, sure hope it's just a minor cleaning and function exercise:beer:
I still say rounds downrange with a new weapon is a good thing, break in or not!








but
Yea break it in.

Not a S&W fan aside from wheel guns. I believe all guns need to be broke in and well lubricated. Every AR-15 I built had to have the bolt soaked in motor oil for the first 100 rounds or it wouldn't fire. Hunting rifles need to have the barrel broke in before you can really set zero or get any kind of accuracy. Think it as the bullets lapping the lands and grooves.

I normally clean the barrel to get out any left over metal, there is always leftover chips unless it was a Weatherby that get test fired for accuracy. Clean them anyway. Shoot 5 rounds, clean the barrel, shoot 5 rounds, clean, shoot 10 rounds and clean and then, only then will I try to zero. I try to put at least a few more rounds down range if I can. Now don't get me wrong, the initial 20 are used to get on paper and work towards the zero.

While I am on the subject, I fucking despise people who think you can't get dead nuts accuracy out of a "cold barrel". In my life, you fucking better be able to get max accuracy out of a cold bore. What the fuck are you going to do? Fire a shot over a person or animals head to heat the barrel and then go for the kill shot? In my world, hot barrels start to walk. If you are a sniper, you better know that barrel like the knot on the back of your head and know which direction it will walk off on you so you can account for it.
 
Is it just a picture thing or does something look funny about that firing pin hole in the first picture?

Barrel break-in isn't really a thing. You may be referring to fouling shots on a new barrel and after cleaning.

Cold bore shot inaccuracies isn't a thing either. Most of it, if it's seen, is from the shooter being unsteady on fundamentals and not locked in/ready
 
I wrote a huge response trying to explain a few things but decided I didn't want to put my shit out on the internet so I shall respond with a "I will have to disagree with you" instead. If you are interested send me a PM.

If you have to soak your bcg in oil for it to work, then something is wrong.

Barrel break in is also a myth. You should clean any firearm before using it.
I have had and shot a ton of ar type rifles and never had to soak the bolt in oil.

Ryan Cleckner talks about "cold shooters", so he lines everyone up to take a cold bore shot at 100 or whatever, they go check the targets. Next day 10 minutes of dry-fire, then a cold bore shot. Yeah, everyone had a vastly improved shot on the second day.
 
Muscle memory is key to 1 shot hits. I should buy a gun before they are all gone.

I did a gig for Nike Golf one time, and Sean Foley, who was Tiger Woods swing coach for many years talked about muscle memory, and corrected the term by saying what you're doing is building neural pathways through repetition. He calculated that it takes several billion neurons all firing at the correct time to make a perfect 300yd tee shot. Anyway, after the event was over and I was getting the microphone back from him, I said, "I've done a thousand of this type event, and usually they're full of BS, buzzwords and generally boring, but I really enjoyed your presentation and I don't even play golf." He said, "Well that's what you get with a PHD and a bong." :laughing:

I don't get the m&p craze, at least not the shield. Couldn't hit shit with it compared to the 365 and 43x.

Only S&W I own is a M&P AR-15 22lr. That thing will eat whatever ammo I toss in it and is very accurate for a pos. I haven’t ran it for a few years now with the ammo shortage and it lives to go through a lot of ammo fast. At least 22lr can be found now but sadly it’ll never be at the low prices we used to enjoy years ago

I figure get what you want now or risk losing that chance due to the commies. I’m comfortable where I’m at but I did pick up a beretta M9A1 22lr pistol the other day. Cheaper to run then my 92FS 9mm

I did the same with my Walther 9mm that I use in comps, got the .22lr version for training, same size, same sights, same controls.

Barrel Break In - Christensen Arms

christensenarms.com christensenarms.com

I am not here to convince you of anything but I think you do people a disservice by making statements like that. Maybe you have only owned shit rifles or didn't care about accuracy that much. I don't know. Maybe you are from the west coast and think people who carry with one in the chamber is insane.

Christensen Arm's makes very fine and accurate rifles. They lap their barrels which mass producers do not do and they still have a break in procedure. Are they crazy or misinformed? Most rifle manufacturers do have break in procedures if people bothered to look instead of going to Walmart to pick up their gun and then go out and sling 100 rounds out of it.

Now I am NOT referring to MOST AR's, AK's and other round slingers. I didn't break in my AK last week because that gun was not bought or ever meant to be an accurate rifle. The barrels on those types of guns get too hot and begin to erode pretty quick. I don't care what they coat them with, when you get steel hot and send projectiles through it, it is eroding your rifling. The powder erodes the throat. They were never meant to be precision shooters. I have a Black Hole heavy barrel on my AR-10 and I did break that barrel in because it was built to be a precision shooter and the manufacturer recommended it. I do not intend to smoke check the barrel every time I shoot and will only shoot slow limited strings from it.

Back to the OP's issue. If he lubed the piss out of that gun and ran a few boxes of ammo through it and cleaned it in between, it would most likely begin to function properly. Probably couldn't hit the broad side of a barn with it because S&W. Anytime a precision item is massed produced, there are going to parts out of tolerance. Shooting and oiling hones down defects and machine marks and will eventually smooth out the defects permitting proper operation.
 
Information from a Quality Manufacturer about breaking in a weapon, I read that as



Clean your shit WELL!
Amazingly new does Not mean Clean:flipoff2:
Next rebuttal?:beer:

How did the detail strip go?
I really think it broke in after 75+- rounds but......
 
Dickweed, your name seems to be fitting.
Three of my friends have had to send their rifles back to Christensen for poor accuracy.
You will get the most life out of A barrel if you do not shoot it very rapidly the heat accelerates wear. Depending on barrel material machining process and coating have a lot more to do with accuracy and longevity than some bs process of shooting 1 round running a patch. Shooting two rounds another patch, ect.
Most of the worn out or failed barrels I have seen are from corrosive ammo and not properly cleaning after it. The next most common failure is from shooting "hot" or very high velocity loads which burn their powder in the barrel and creat more heat and wear than tamer cartridges, but that doesn't have anything to do with barrel break in.
