Just got my new M&P .45.



After a quick familiarization and disassembly I decide to load a mag and champer a round. No joy.



The round jammed halfway on the magazine and half way up the ramp. Is this just new gun stiffness? A non broken in ramp?



I don't think it is the magazine, the springs are plenty stiff.



I suppose it could be the ammo, magtech, but somehow I don't think so.



Should I take the pistol back to the gun shop? Or should I try a different type of ammunition? Is anyone else experiencing this problem?

Did you use the slide release or did you use the "slingshot" method to release the slide? If the latter, make sure you're not "riding the slide" forward because that can cause rounds to fail to get up into the chamber.

After reading your question I did a test.



3 rounds, only with the slide release.



2 chambered, 1 misfed.



I'll take her to the range tomorrow and maybe my questions will be answered. I think she needs to be broken in. Though I am worried about her feeding.

I always clean and over lube new pistols of any kind before i break them in with 2 or 300 rounds the first outing.

i bet it is ammo related

buy some ww white box if it won't feed that something is not right with the pistol

fwiw, mine will not chamber a round reliable with the slide release. I need to slingshot it.



YMMV, ET AL, ETC, and all sortos of other disclaimers that are not really relevant

You should be fine, go shoot it and give us a report. +1 on clean and lube before going out.

You, sir, were/are abso-tutely right



Magtech, Brazillian made, is the culprit. Comparing the Winchester, Remington, and Magtech side by side it looks like the Magtech is slightly taller that both the win and the rem. I'm beginning to suspect that the sales person accidentally sold me some revolver ammo instead of ACP.



The two American made rounds are identical except that metal jacket of the Winchester seems pinker than the Remington. Both the Winchester and the Remington fed like a dream. So it looks like my M&P is an expensive date.



On a side note the indoor range I was at had a gunsmith. I told him about the feeding issue and he checked my firearm with some S&B ammo. After he fired about 10 rounds he said that the feed ramp looked fine. He mentioned that "those M&Ps shoot great, hardly any muzzle climb at all."



Sweet sweetness.
