not limp wristing. I have a cabinet full of handguns, this is the only one I have a problem with.

it doesn't eject the spent round. I have to remove the magazine and shake out the spent round, it tries to feed another round while the spent one is stuck.

I have 3 different mags, the one that came with it and I bought 2 more, all do the same.

It's not my carry until I get this fixed or just get rid of it. Yes, I have the M&P in .45 never had a problem with that weapon. I also have 3 SIGs 2 in 9mm and one .40, wife carries a Sig .380 never had a SIG problem. I have a couple of Colts, one of them is the Combat Commander in .45 and the other is the Double Eagle I got from the guy they booted from here for not obeying the selling rules. Both Colts are fantastic pieces of gear, tanks both of them.
