Glock 41

The Glock 41 is Glock’s full-size long-slide .45 ACP pistol — a competition-oriented .45 ACP service pistol with a longer sight radius and barrel than the standard Glock 21 in the same .45 ACP chambering. The G41 delivers 13+1 capacity with longer barrel velocity and improved practical accuracy from the extended sight radius. Impact Guns carries the Glock 41 Gen4.

The Long-Slide .45 ACP Glock

The Glock 41 fills a specific role in the Glock lineup: a long-slide .45 ACP service pistol with the longer sight radius and barrel of competition-oriented Glocks (the G17L, G24, G34, G35) but in .45 ACP. The 5.31-inch barrel adds velocity over the G21’s standard 4.61-inch barrel, and the extended slide’s longer sight radius produces measurably better practical accuracy from open sights. For .45 ACP shooters who prioritize accuracy and competition use over compact carry, the G41 is Glock’s answer.

Specifications and Configuration

The Glock 41 ships in Gen4 configuration with 5.31-inch barrel, 13+1 capacity in standard magazines, an interchangeable backstrap system for fitting different hand sizes, and an accessory rail for light and laser mounting. Total length is 8.9 inches, weight is 27 ounces unloaded. The G41 fits standard G21 magazines for higher-capacity reloads (G21 magazines hold 13 rounds same as G41; the extended G21 SF magazines and similar fit as well). The slide is approximately 0.7 inches longer than the standard G21, accounting for the long-slide designation.

Glock 41 vs. Glock 21

Both fire .45 ACP from the same frame size with the same capacity. The differences: G41’s 5.31-inch barrel vs. G21’s 4.61-inch barrel, G41’s extended slide and longer sight radius, slight velocity advantage from the longer barrel, and the G41’s overall length increase. For pure service or defensive use, G21 is the practical choice — shorter slide, easier holster compatibility, broader holster selection. For competition, target shooting, and any application where sight radius and barrel length matter, the G41 delivers measurable advantages.

Competition Applications

The G41 is positioned for USPSA Limited, IDPA, and similar action pistol competition formats where .45 ACP is the preferred caliber. The extended sight radius improves practical accuracy, the longer barrel adds velocity, and the standard Glock magazine compatibility supports the high-capacity reloads competition demands. For 3-gun shooters who run .45 ACP, the G41 is among the more competitive Glock options. For shooters who prefer 9mm for competition (most do), the G34 or G35 in respective calibers serves the same long-slide role.

The .45 ACP Question

The G41 is a .45 ACP pistol — meaning ammunition cost is higher than 9mm and capacity is lower than 9mm equivalents. For shooters specifically committed to .45 ACP for personal preference, defense, or competition, the G41 is the long-slide answer. For shooters open to caliber choice, 9mm equivalents (G34) deliver more capacity at lower ammunition cost with comparable practical accuracy from similar barrel and sight radius. The .45 ACP preference is the prerequisite for the G41 making sense.

Frequently Asked Questions

What is the difference between Glock 41 and Glock 21?
The G41 has a longer 5.31-inch barrel and extended slide producing a longer sight radius. The G21 has the standard 4.61-inch barrel and shorter slide. Both fire .45 ACP from the same frame and capacity (13+1). G41 for competition and target use; G21 for service and concealed carry.

Does the Glock 41 use the same magazines as the Glock 21?
Yes — the G41 uses standard G21 magazines, with the same 13-round capacity and physical dimensions. Extended G21 SF magazines and similar high-capacity options also fit. This magazine compatibility provides broad reload and accessory ecosystem.

Is the Glock 41 a good carry gun?
Not particularly — the G41 is designed for competition and target use with a longer slide that increases concealment difficulty over the G21. For .45 ACP concealed carry, the G21 SF or G30 are more practical choices. The G41’s advantages (longer sight radius, barrel length) come at the cost of compact carry compatibility.
