What is it about your P-09 that makes it so special Joe? Custom work or is it just inherently accurate?
I bought mine right after they first came out and put a red dot sight on it shortly afterwards. It has a few CGW parts in it, but the mechanical lock up on two P-09's and one P-07 is excellent from the factory, and I haven't touched the lockup dimensions, not that I would know what to do to one to "accurize" it anyway. There is something unique to the CZ barrel lugs, timing, and machining tolerances that provide perfect lock up each time the gun cycles, whether the first round chambered with a slide release or slingshot, doesn't matter. I used to think my particular P-09 must be a freak, but my second one and a P-07 from Academy Sports near my house are essentially as good mechanically. My conclusion is that a P series gun with a CGW hammer and nothing else can provide results that most people would have thought had to be from a high dollar custom 1911. Mine have not been to the CGW shop. I've installed the CGW hammers in each one, made some spring changes in the P-09's to work with the low power factor ammo I typically shoot, and that is about it, besides putting a red dot on a beavertail mount on them when I want to shoot bullseye or long range.
I would expect similar results from almost any P-09 or P-07 I could get my hands on and put a 3 moa red dot and a CGW hammer in. (Along with some JB-Weld and Sugru, perhaps.)
CGW could tell you what the percentage is of P series pistols they have worked on that were sloppy in lock up. In all the reviews I read when the P-09's first came out, the universal comment was how "accurate" the gun was. After a few hundred rounds through mine, I became a believer, and I didn't even like polymer guns. After 10,000 rounds through my red dot equipped P-09, and several thousand through each of the other two polymer hammer guns, I would say my particular guns are not special. They must be typical of CZ's modern late model handguns, in design and manufacturing, and that means they are excellent.
Hate to sound too much like a fan boy, but my own personal results have been pretty darn good with these pistols. They aren't your typical sloppy plastic service gun, near as I can tell.
