Frequently Asked Questions

What were the key performance differences between Speer Gold Dot .45 G.A.P. and .40 S&W in the ballistic gel test?

The .40 S&W (165gr) averaged 1149 fps and 15.5 inches penetration, while the .45 G.A.P. (185gr) averaged 1068 fps and 14.25 inches penetration. Both showed excellent expansion and nearly 100% weight retention.

How was the ballistic gel test conducted for the .45 G.A.P. and .40 S&W ammunition?

The test involved firing rounds through a heavy clothing barrier into clear ballistic gel blocks. A LabRadar chronograph measured average velocity and muzzle energy, and penetration depth and projectile expansion were meticulously recorded.

What is the historical context of the .45 G.A.P. cartridge?

The .45 G.A.P. was developed by Speer engineer Ernest Durham for Glock around 2003. The goal was to replicate the power of the .45 ACP in a smaller pistol frame and magazine, similar in size to a 9mm case.

Which caliber performed better in the ballistic gel test, .45 G.A.P. or .40 S&W?

Both calibers performed exceptionally well. The .40 S&W achieved slightly deeper penetration, while the .45 G.A.P. showed slightly greater expansion. The choice between them may depend on specific self-defense priorities.
