45 GAP AMMO IN BULK SHIPS FREE!

45 GAP ammunition was especially designed for Glock and "GAP" actually stands for "Glock Automatic Pistol". Engineer Ernest Durham designed the 45 GAP round as a cartridge that would be as powerful as 45 ACP but would have a stronger case head to reduce the chance that the case's neck would blowout. 45 GAP is also more compact, making it an ideal choice for shooters looking for a very strong cartridge that can still be easily concealed.

The GAP chamber in the firearms allows these pistols to be more narrow than their 45 ACP counterparts, which is ideal for shooters seeking a self-defense load and corresponding firearm.

If you’re carrying 45 GAP for self-defense, be sure to look for a jacketed hollow point projectile (JHP) as these rounds have a bullet that will expand on impact. For range shooters, you should be just fine with a full metal jacket (FMJ) round.
