While I picked up a LNIB G-39, 2 mags, box and all, maybe 25 rnds through her as it looks new, for the New Year! I got a deal I think, I paid $400.00! I figure I would try the gap and use the G-39 for Conceal Carry. Just thought I would share and it seems to be like the G-27 just with a bigger slide. I got some lawman FMJ, I also got some 165 gr JHP Mag-Tech. I was also wondering what kind of ammo is most reliable?? Any input from the Glock gappers is appreciated!!!!
