Notes
The G21 V MOS shares identical dimensions and weight with the Gen5 MOS variant: 735g (25.93 oz) without magazine, 205mm overall length, 117mm barrel. The V-series represents Glock's latest generational update succeeding the Gen5 platform. Magazine capacity remains 13 rounds of .45 ACP with optional 10-round magazines for restricted jurisdictions. The V-series maintains the same trigger pull of 26N established in the Gen5.
Background
The .45 ACP cartridge has survived every attempt to replace it for over a century, and Glock's continued investment in the G21 platform through the V-series proves the old warhorse still has commercial legs. While 9mm dominates law enforcement and military contracts, a devoted segment of shooters insists that nothing short of .45 caliber will do. The G21 V MOS gives them the most technologically advanced .45 ACP Glock ever made, with optics capability that bridges the gap between traditional big-bore shooters and the red-dot revolution.
