I just bought a 9mm P30, V3, and I really like it! I have the urge to tinker though, and I can't help but wonder if I could do my own trigger job or trigger module change. I own the Glock Ptooma guide, have done it all w/ Glocks, and am basically an "un certified" Glock armorer. Anybody know of an HK equivalent to the Ptooma guide? Or have any thoughts on "doing it yourself" with this pistol?
