I would, I used to own a G38 and it shot well. You can find the GAPs on GB for usually a pretty good price and you can find brass too, and ammo as well. I don't have one because I don't need it, but there's nothing wrong with the GAP.
Still begs the Q: When the feces hit the rotating air device, would you rely upon it in lieu of a .45 ACP considering ammo availability? Even if one reloads, one better have a good stash of components. Any .45 GAP max load can be easily exceeded in a .45 ACP case.
I can understand (somewhat) why someone would want it just for S&G or as a collector piece, but I don't have the money for that type of firearm, let alone the dies and casings to reload it.
Your username seems to allude to a preference to the .45 Colt cartridge.
I would much rather have a 1858 Rem New Model .44 or a Colt 1860 Army .44 with a Kirst .45 cartridge conversion cylinder for each. Much more powerful than any .45 GAP. Yes, apples and oranges.
Otherwise, any (1911 or other) .45 ACP will outperform an .45 GAP.
It was just one of Gaston's last gasps to make some money with his pistol frame size.
I have shot Glocks and don't care a bit for them, just like I didn't care for the alloy frame Para Ord P-14 I once owned.
1911 .45 ACP steel gun all the way. Simple to shoot, repair, and carry if one bothers to obtain knowledge about the gun.
