CZ99 came in today, and she's a dirty girl. Grime, grease, and dirt are packed in pretty well. Finish is roughed up primarily on the frame, but I had planned on DuraCoating the piece anyhow.

Ran 15 rounds through, half of them failed to fire. Noticed the pin strike on the primer is way out of concentric.

After inspecting the bolt face, I noticed a ring of shaved brass stuck inside the firing pin hole which was pushing the pin travel out of center. Ran out of daylight so I didn't get to test after cleaning the hole out.

Trigger was quite nice in double action, moderate travel and clean/light break at about 4lbs in single action; pleasantly surprised.

Now I just got to decide what color scheme to paint.

Well, I ain't happy.

Misfires were not due to crap in the pin channel. I even took the whole firing pin assembly apart, cleaned all the gunk and crud out.
I got to looking at the dark ring left on the bolt face which outlines the primer pocket from the cartridge; you can see how far off the pin strike is from the center.

Looks like when the slide and barrel lockup, the cartridge position simply isn't concentric with the pin.
I'm sending it back, hopefully AimSurplus has a trouble free return policy.

Keep us posted. I want to see how well or how badly aimsurplus handles this. I've bought several guns from them and hope they treated you good.
