A: Thanks for reaching out Tracy! You have quite the treasure there. I would first advise you to forget that 45 GAP exists completely. The 45 GAP is a completely different cartridge than the 45 ACP which your father's M1917 revolver is chambered for. The M1917 was adopted by our military to supplement the M1911 pistol, which is why it is chambered for the same type of ammunition: 45 ACP. Compared to the M1911, the M1917 is not as sensitive when it comes to which kind of 45 ACP amminition it will fire. Still, if you would like ammunition which is very close to that which would have been issued by the Army, then I advise any cartridge with a 230 grain bullet and ~830 fps muzzle velocity. To that end, I would recommend Remington UMC for target practice:
If you would like ammo which is suitable for personal protection, then I highly recommend this police grade 45 ACP by Federal Premium:

A: Thanks for reaching out Mike! I'm afraid 45 GAP won't work in your handgun. It's loaded to a much lower chamber pressure so it's not going to get anywhere near a 45 Super's muzzle velocity, and the 45 GAP's different exterior dimensions mean it wouldn't chamber properly – even if it fired, the accuracy would be all over the place. I'm sorry that we haven't got any 45 Super in stock right now, but we do update our inventory all the time. I hope you'll check back in again soon!

A: No sir, I'm afraid not. The only suitable ammo we have in stock for your 1911 is on our 45 ACP page: luckygunner.com/handgun/45-acp-ammo

A: No sir. The 45 GAP is a relatively obscure semi-automatic pistol cartridge developed by Glock and intended to supersede the 45 ACP. (It didn't succeed at that goal, but enough people do use it that it has remained in production.) For your Judge you want either 45 Colt (aka 45 Long Colt) or 410 Bore (aka 410 Gauge) ammunition. I regret that we haven't got any 45 Colt in stock at the moment, although we have got an option for 410 Bore: luckygunner.com/shotgun/410-ammo-shells. We're a bit short stocked right now because of the ammo drought, but we're still getting in new ammo all the time. I hope you'll check back in again soon!
