I've had 1, on a reload, CCI primer, they are also known to be a hard primer
IAShooter said:I've only purchased 1 box of factory ammo so far and it was WWB.
I've had the same issues you are experiencing MP40Fan.
Lots of double feeds and barrel jams.
It's been bad enough that I have definately purchased my first and last box of WWB.
The LEO's at the S.O. that I work at are qualifying today.
A few of them are going to take my M&P and put it to a serious test.
They've been asked to keep track of any feeding problems and any light primer strikes.
I should have a report tomorrow.
Any light strikes and I will be contacting Smith & Wesson.
As far as the winchester primers, I've never had a problem, with the exception of this 1000 lot.
When I do get a light strike, I inspect the primer and it appears to have a pretty good impact on it. I cycle it through the magazine again and 90 percent of the time it fires.

When I first got mine I had a lot of misfires. Sent it back to S&W, they fixed it and returned it in a timely manner. Worked perfect after that. Haven't had a misfire since.

iskiuskiweski said:I just brought my 40 back from the range, so in doing my usual cleaning I decide to go ahead and remove the striker assembly and clean it out and inpect it for possible wear issues. I was not experiencing a problem, I have just put about a thousand round thru it and the striker assembly had not been cleaned yet. When I removed it, I found an accumulation of what apeared to be brass shavings. Not sure where they came from, other than flakes from the firing pin making contact with the primer and carring shavings back with it. As far as I know there are no brass parts in the striker assembley, unless there is a bushing in there I can't see. I can see after a while if left unchecked it could cause problems. Keep em clean!
