Congrats on the new pistol, I'm pretty sure 0-8-1 is the new one. Safe is in the bedroom and the wife is sleeping and I don't feel like getting my ass kicked this morning so I'll have to check mine later. My gen 4 G27 runs fine on 165g, 155g, and 180g. I like the 165g the best in .40 though. Right now though I have 125g Gold dots in it. Although I have a 357sig barrel in it.
