45 GAP Bullets

45 GAP Bullets for Reloading

The 45 GAP is Glock’s first attempt to introduce a new cartridge to the commercial market. You don’t need to guess which cartridge the 45 GAP was meant to improve upon, and indeed the 45 GAP matches the 45 ACP’s power while reducing the chance of a case neck blowout.

The original max bullet weight for the 45 GAP was 200 grains, which is loaded to a higher pressure than 45 ACP to give it equivalent performance. The 45 GAP’s max pressure is 23,000 psi, about nine percent more than the 45 ACP, to make this possible. Since the 45 GAP is a smaller round, its greater pressure is achieved solely via more powerful powders. The 45 GAP has since been determined capable of firing 230 grain bullets, and load data for 150, 160, and 185 bullets are available as well. The 45 GAP’s bullet is .451 in diameter, so finding the correct bullets for reloading is as simple as finding 45 ACP component bullets.

The 45 GAP is a little shorter than its predecessor, with a .755 inch long case instead of .898 inches. Glock intended this to permit the design of smaller handguns. You could theoretically trim down 45 ACP brass to make 45 GAP brass, but their lengths alone aren’t the only thing that make the two cases different. You’re better off loading once-fired 45 GAP brass or investing in brand new cases.
