What ammo have you had issues with?

[agksimon]

My M&P9 compact had problems with the extractor grabbing Winchester white box 100 round packs. I filed a slightly more aggressive hook on the extractor and never had a problem with them after that.

...my Glock has never (repeat) never failed to fire.

I'm glad you have had good experience with your gun. However, it is only one data point. The two Glocks that I owned also ate every round I ever put in them and never had a failure. Still, only one data point.

When I say that I've seen more failures from Glocks it's because I've literally seen more than a hundred in the last year or so. In classes I've attended and some that I've taught myself, the Glock has been the most prevalent gun to have malfunctions.

Now, to be fully true in the data I'm presenting, I have to caveat that with the fact that the Glock is by far the most common. In a class of 40, typically 20 of them are Glocks. I'm not saying this is normal across the board, it's just what I've personally observed. In those same classes, there were never more than 2 1911s in any one class. So, I'm sure that skews the data if you try to extrapolate what I'm saying to include all Glocks everywhere. I'm just reporting what I've seen.

It should also be noted that this surprised me very much.

I've fired Federal, Winchester white box, Wolf, Blazer brass (and aluminum), Sellier and Bellot, PMC, Magtech, Remington UMC, and even some reloads through my shield 40 and my wife's shield 9. Never had any issues, but haven't tried any of some of the ones mentioned on this thread. Never tried Tula, but I hear that it doesn't work well in the M&P line.

My M&P 9mm FS hates CCI Blazer Aluminum. The cases eject between 5 and 6 o'clock. I've had some eject at 7 o'clock.

 

[Vinney47]

My m&p 9's have been flawless except for with some MFS garbage - and it gave both mine issues, plus a glock 19 and a ruger SR9 of family members that also were/are issue free since then.

I have an M&P 22. As we all know, 22 ammo is somewhat unreliable The one that stands out as the worst for me is Remmingtor Thunderbolt. It has to be the dirtiest ammo around. After 100 rnds or so the barrel begins to lead up badly and the rounds key hole the target and accuracy is gone.

 

[mikehilliard]

I use 4.7gr 231 under a 115gr plated RN bullet and 4.3 under a 124gr RN. Haven't had a problem with either in over 30K rounds shot. I still have stock springs in my M&P's.

Tell me is it usual for a recoil sprint to measure more than 16#? If this is normal then I have a normal recoil spring. The total number of rounds sent downrange to date is just under 130 rounds of which 60 were factory from Federal, which by the way are factory 115 RN. The remaining 70 required hand extraction by pulling the action open. Many were stovepipes which led me to consider a softer spring.

What do you think it will take to break in the firearm, or do you think it may be a more difficult task?

If this is a brand new gun, have you cleaned and lubed it? Sometimes new guns are stiff and somewhat underlubricated. I haven't had a similar problem but I shoot considerably more (about 200-250 in a normal day). If your gun is adequately lubed then stovepipes indicate either too heavy of a spring, something binding in the slide, or underpowered ammo. Kinda difficult to diagnose over the internet, but I'd start by cleaning and lubing it, run a few hundred factory rounds through it and then re assess the situation. Good luck.

Some time back, got a "deal" on some IMI 9mm. All I can say is, I hope the Israeli Army gets better stuff than this. Some under powered, some without primers, some without flash holes on the primer pocket. The last straw was two bullets in a row getting stuck in the bore of my Shield. Cleared one, put the mag back in, the next one stuck too. The biggest danger was the bullet was far enough down the bore for the weapon to cycle. Luckily, I was paying attention. Had I touched another off with a plugged barrel,,,,,,

That's surprising, usually IMI is great stuff, their 9's were always pretty hot. I don't hesitate for IMI ammo if the price is right.

I've heard Amerc loaded IMI brass, perhaps you got some of that?

I went to the range today...fired 100 rounds each in my Glock 26 and Shield9...using WWB 115gr ammo from Wal-Mart....guess which one had a FTE (only one)....just saying...both pistols have over 1000 rds thru them....

 

[tectrry]

I've stayed away from most name brands (simply due to cost) and over the past year have used about 5K rounds of 9mm and 2K rounds of .40 through my M&Ps and the majority has been HSM and Freedom Munitions. I think the HSM is a little more consistent and the Freedom sometimes seems a bit "hot" (too much powder?), but have not had a single problem with the ammo. So my feeling is that if it eats the cheap factory reloads that i put through it - it would probably eat anything.

 

[dp2826]

Three trips to the range with my new Shield 9. First trip had 2 FTE in the first magazine with total of 50-60 rounds. Second trip had 2 more FTE in about 200 rounds. Third trip only had one FTE in about 200 round. All Winchester White Box. I'd like to try some different ammo when I find it, and some defense ammo.

 

[Philadelphia Patriot]

I had a Ruger SR40c that didn't like PMC .40 fmj. I did some research online and a lot of people had problems with PMC due to "hard primers".

 

[Johnmuratore]

Anyone have a clue why the WWB shows up so often as a problem? Winchester used to be known as an extremely reliable ammo manufacturer in the not so distant past.
I've got some I'll have to compare to the 50 rd packs.

Thanks for the excellent thread.

If you look at the underside of the rim on Winchester white box, as compared to other brands, it's not as flat, so the extractor has more of a chance to slip off. If you install an Apex extractor, with a more aggressive hook, it won't slip off.

 

[dp2826]

Not sure if Winchester changed the rim at some point. Why wouldn't Smith use a better extractor? Any other 9mm I've shot works reliably with WWB.

Fiocci 170 grain FMJTC (truncated cone) no good for the M&P .40

Talk about frustrating. Had six boxes of this stuff and went to shoot it with my M&P .40 which I have had 4 years. Not one failure in 4 years. Every 4-5 round it would FTF. Jam up trying to get up the ramp. Went home thinking my gun had problems. Went on the internet and shazamm! Truncated cone.
TC. Bad news with the M&P .40. Don't touch it. Nothing but problems. They can keep there truncated cone.

 

[jagular]

I've had 3 stove pipes (out of 200 rounds) out of Winchester white box. I shot some of the same this last weekend and was 100%. Could've been undercharged/overcharged rounds of that lot. All other brands: federal, fiocchi, brassmaxx, Remington have been 100%.

 

[mountaineer40]

My M&P 9 has cycled everything I've put through it. All types of Brass (Remington, Winchester, Winchester NATO, Federal) the high end hollow points, and steel cased ammo. Just this weekend I put some Tula through it, fired all 50 rounds. I've had my M&P 9 for over a year and have had no malfunctions and I'm well past 1,000 rounds. My 4006 however hates Winchester Whitebox. malfunctions at least one time in an eleven round magazine.

 

[Travis15R]

Everything has gone bang in M&P40Pro and Shield9. Mostly shoot factory reloads (laxammo.com) and Hornady Critical Duty, but have shot FMJ Blazer, Remington, Winchester white box in both with no issues.

I just got a shipment of 500 rounds of LAX reloads for my .40 last week.
