I running 230gr. Magtec ball,On the last go around out of 50 had 1 Sig mag with only 7 of 8 and for some reason when I slingshot the slide round wouldn't ramp up.Was half was and pinched with slide on case I pushed round to the back of mag and tried again same thing.Rmoved round pulled slide back chamber round shot rest of mag without problem.Had another where slide locked back with last round in mag [which happened before].Had less FTF this time.Before I took it for a spin took it apart and cleaned I use CLP always,put weaponshield on slide.100 rounds seems to be running better.Guy at the shop said it took his Kimber a few hundred rounds to break in.I want to break this in really bad to make it my carry pistol.It is easy to shoot feels great in my hand.Shreads bulls,with bedwetters wearing body armor wanted to step up from 9mm XDM I had.I also carry S&W bodyguard revolver when doing alot of driving.Different tools for different jobs.Use a Blackhawk Sherpa holster for 1911 & XDM I like the retention feature.I get back to work brother Larry [Hemi] is 1911 wizard so he'll take it to the next level.Great pistol. <thumbsup>
