Frequently Asked Questions

How did the Speer Gold Dot .45 G.A.P. and .40 S&W perform in ballistic gel tests?

Both Speer Gold Dot rounds showed excellent performance. The .40 S&W (165gr) penetrated 15.5 inches and expanded to .659 inches. The .45 G.A.P. (185gr) penetrated 14.25 inches and expanded to .700 inches, retaining nearly 100% of its weight.

What are the key differences between .45 G.A.P. and .40 S&W cartridges?

The .45 G.A.P. has the same diameter as .45 ACP but a shorter case (19mm), similar in length to a 9mm. It requires higher pressure to achieve its performance. The .40 S&W is a more common cartridge with a longer history and wider availability.

What were the velocity and energy figures for the tested Speer Gold Dot ammunition?

The 165gr Speer Gold Dot .40 S&W averaged 1149 FPS with 484 ft-lbs of energy. The 185gr Speer Gold Dot .45 G.A.P. averaged 1068 FPS with 469 ft-lbs of energy.

Is the .45 G.A.P. cartridge still relevant for self-defense?

While the .45 G.A.P. performs well, as demonstrated in this test, it's often considered a niche cartridge. Its performance is comparable to other popular self-defense rounds, but the widespread availability and established platforms for .40 S&W and 9mm make them more common choices.
