Reloading The .45 GAP (Glock Automatic Pistol)

(WC= WadCutter, SWC= Semi-WadCutter,
HP= Hollow Point, RN= Round Nose), SP=Soft Point
(JHP= Jacketed Hollow Point and if GC indicated, means Gas Check at bottom of lead bullet)

Loads for .45 GAP (Glock Auto Pistol):

This new round is like a short version of the .45 ACP. It’s a shorter case for use in smaller magazines in smaller handguns. Loads can equal its big brother, the .45 ACP. It is well suited for very compact autos.

(Note: These are near MAXIMUM loads (unless otherwise indicated as a START load), you should use 10% less to start, or use the START loads.)
(See note on Powders below or read all about various Powders.)
Bullet sizes vary from .451″ for jacketed to .452″ for some lead in diameter. Due to different barrel lengths, type of bullet, seating depth, primer type and other factors, you may not get near the FPS charted. It is just a guide and the reason you should start under these charges and work up.

Discussion: The small case and short powder burning time of the .45 GAP needs a faster burning powder, like Bullseye, Clays, 231, or Unique. Round nose bullets feed better in autos. More loads for the 230 grain and heavy bullets will be added later. However, the SWC has a round enough nose that it feeds well in most autos and makes a cleaner target cut-out. Whether you use the lead or full metal jacketed bullet is up to you, but the lead is, of course, much cheaper if you shoot very much. Because of lead fumes in the air, you should use a jacketed or copper plated bullet indoors. Copper plated lead bullet loads vary slightly from all lead bullets, and you should contact the bullet company for loads for plated bullets.
