These 1911's come in three styles, pkz, pkzse, pkzsew, I bought the pkzsew about two months ago. I have fired ninety rounds and have had one failure to feed, it was a 185 gr. JHP, zero FTE. I didn't trust the stock mag, so went and bought wilson combat mag's (47D). Fit, finish are excellent, only thing that makes nose is the magazine, in which, all mag's do once inserted in a firearm. I will be buying another one or two, just total in love with this 1911. Buyone, you won't regret it.
