I shot one of the two PC1911s today. They both have the Koenig hammer. The Koenig hammer is just lighter and is designed to have less effect on your POI as compared to your POA, from the weight of the hammer falling. Mr. Koenig notices the difference.
What I learned from shooting this gun is that I'm not Mr. Koenig. ;f
The gun is a sweetheart though. The slide to frame fit is smoother than seal poop on an ice flow with absolutely zero side to side or up and down play. I like the high cut front strap and 30 lpi checkering. Together they make the gun feel like a Baer. The grips are nice, however the checkering on them isn't as sharp as I'm accustomed to.
I shot 200 rounds of Federal American Eagle ball ammo with the supplied Act-Mag and some Metalform 8 rounders. The gun worked perfectly until about round 175 when a round went about 3/4 of the way into the chamber, but not fully into battery. The remaining 25 rounds were perfect too.
I mostly shot for groups at 15 yards to get the sights dialed in for me. They came shooting a little left and a skosh high, which was simple enough to remedy with the high quality Wilson adjustable rear sight. I also ran 40 rounds of rapid fire and found the gun quick to recover with a very nice trigger reset.
I was a little crunched for time today so after the gun cooled I put it back in the FFL's safe without cleaning it or inspecting the gun's internals.
Therefore my initial impressions were confined to exterior fit and finish and the bit of shooting I was able to do.
In a nutshell I came away very impressed with this pistol and can hardly wait to go back and shoot it some more. Next time I'd like to compare it to my Baer UM 1.5 and Springfield TGO 1, which are the two other adjustable sight 1911s I own. I think the PC1911 will compare very well.
