I bet it is a recoil caused issue.

I'd polish the followers and remove any sharp edges that can catch the punchouts.

Update 3:

Installed 22lb. recoil spring assembly from Galloway. No difference at all. Still consistently jambs the second to last round from the magazine no matter what the ammo.

Wondering what to do at this point. I'm going to try and run the standard magazine spring with the 22lb. recoil spring and see if that does anything. I'm also going to look at it tomorrow under better lighting and see if polishing the feed ramp or the underside of the barrel hood might do anything.


I would return it to factory configuration and send it back again. Provide a detailed list of every type of ammo you used and that it happens every time with each manufacturer of ammo. If you could include a link to a video of it happening or put one on a USB drive to send in, I would do that too.

@2000Z-71 Thank you for keeping us updated.

I have been following your thread.

I am somewhat leery of investing into M&P 10mm

There is a reddit thread of somebody who went
through very similar iterations.

His 'working configuration'
is standard recoil spring + extra power magazine spring.

Apparently there is a magazine design issue.
