I know a lot of people "frankenstein" their glocks...ie G36 slide on a G30 frame etc etc. Sooo,.... I badly want a gen 4 G38, but don't see them producing one in the near future, due to the caliber. My question is, can I put a current G38 slide on a gen 4 G23 frame? Then simply use G38 mags. Much thanks in advance. PS before anyone asks,.."why a 45 GAP"....its because I LOVE it & the smaller grip on the gen 4 frames.
