Frequently Asked Questions

What is the main difference between 9mm and .45 ACP from a shooter's perspective?

From a shooter's perspective, 9mm generally offers faster follow-up shots, higher capacity, and easier recoil management compared to .45 ACP. While .45 ACP delivers more energy, 9mm often proves more practical for speed and control in drills like the Bill Drill, as demonstrated with the Glock 19 and Glock 30S.

How does recoil differ between 9mm and .45 ACP firearms like the Glock 19 and Glock 30S?

Using a Mantis X10, the 9mm Glock 19 showed significantly less muzzle rise (10°) and faster recovery (0.49s) than the .45 ACP Glock 30S (20° muzzle rise, 0.76s recovery). This indicates 9mm is typically flatter shooting and easier to manage for rapid firing.

Which caliber is faster for shooting drills like the Bill Drill?

In practical drills like the Bill Drill, 9mm typically proves faster. The Glock 19 (9mm) completed the drill in 1.75 seconds, while the Glock 30S (.45 ACP) took 2.11 seconds, highlighting the 9mm's advantage in speed and follow-up shot capability.

What is the importance of training and shot placement over caliber choice?

The instructors emphasize that consistent training and accurate shot placement are paramount for self-defense, often more critical than the caliber choice itself. Mastering fundamentals allows a shooter to effectively utilize either 9mm or .45 ACP, with 9mm offering advantages in capacity and recoil management for many users.
