V1 Controls, Full-Size .45
V1 is HK’s DA/SA variant with the combined safety and decocker on the left of the frame. Dual slide releases and an enlarged magazine release are the other controls you actually use. The grip-to-slide angle is the one HK published as matching a 1911, and the polymer frame takes replaceable backstraps so you can change circumference without changing pistols. HK lists this pistol as supplied with one additional backstrap.
Barrel, Recoil System, and Rail
- Cold hammer-forged polygonal barrel with HK’s O-ring at the muzzle for consistent barrel-to-slide lockup.
- Modified Browning linkless short-recoil action.
- HK’s internal mechanical recoil reduction system — HK rates the reduction at up to 30%.
- MIL-STD-1913 Picatinny rail molded into the dust cover (HK lists four slots on the HK45).
- Fixed sights: open square-notch rear with contrast points.
