I got my P226 metal kit thru Jugglez at
www.airsoftparts.ca. He brought me in a Guarder frame, slide and barrel, recoil spring. A few other odds and ends. He has a 100% positive rep from what I've read and have personally bought from him on multiple occasions. As for the metal kit, it looks and feels kick ass. Full trademarks, good weight, etc. As for firing, without upgrading valves (which I didn't do), I think you may be disappointed. I can't get thru a full mag before I run out of gas. When I do empty a mag, the slide only occasionally locks back. Again probably due to the lack of additional upgrades. I use my stock TM P226 as my secondary, even though I have the metal one. If you do it, think about the full meal deal as far as upgrades go.
