P226 slide not functioning correctly?

[racky]

had the same problem with my ar15 and 1911. turns out it was the cheap magazines i bought for it.

I have the same problem but it only happens to one of the magazine. I suspect that I always fully loaded one of the mags for HD at home so may be that particular one has a weaker spring since it is always being compressed?

I didn't keep track of which one is always fully loaded because I unloaded that mag before heading to the range. All I know is that the gun didn't lock back after the last shot with the same mag because it kept happening to the same person. I have the Navy version so it comes with 3 mags. There were 3 people so we all have our own mag. I am sure it wasn't the problem with how the person holds the gun because the gun locks back every time when I was shooting and when I tried his mag, same thing happen to me.

Is it a P226 9mm? My p228 did this a few times when it was new. A new recoil spring and plinking ammo is probably the cause. It didn't happen when my p226 40 was new because I believe 40 is of higher pressure.

you got a piece of crap sig.

get rid of it.

tell you what... i'll take it off your hands... i'll be nice and give you a couple bills for it...

@ Cato, yes, it is a 9mm. The ammo that I was using is Remington UMC 115 Gr. It's probably nothing major and as long as it goes bang every time I press the trigger, I am happy with it

Lol @ Idvinag. I hate to cause potential injuries to other people so I will just keep my Sig.
