The Umarex MARK IV-M Silver is a premium break-barrel air pistol chambered for .177 caliber (4.5 mm) lead pellets, designed for plinking, target shooting, and small-game hunting. Featuring a full-metal slide and frame with a sleek silver finish, the MARK IV-M delivers solid heft and a refined aesthetic. The rifled steel barrel (120 mm) ensures exceptional pellet stability and grouping, while the integrated adjustable rear sight and fiber-optic front blade provide precise shot alignment in various lighting conditions.

Operating on a single-stroke spring-piston mechanism, the break-barrel design requires a firm 125° backward rotation to cock the internal spring. This intuitive cocking action offers smooth leverage, making it accessible for shooters of all strengths. Once cocked, the pistol produces velocities around 450–500 FPS (0.20 g pellets), delivering consistent power suitable for backyard target practice or pest control. The automatic dry-fire safety and manual push-button safety on the left frame ensure secure handling between shots.

The ergonomically contoured polymer grip features textured side panels and a rubberized backstrap insert, providing both comfort and traction during extended shooting sessions. A generously sized trigger guard accommodates gloved hands, and the two-stage trigger boasts a light first stage followed by a crisp break, contributing to enhanced accuracy. The synthetic muzzle protector prevents damage to the rifled barrel when cocking, and the internal anti-beartrap mechanism prevents the barrel from snapping forward unexpectedly during loading.

Loading is straightforward: cock the barrel, insert a .177 pellet into the breech drop port, and return the barrel to a locked position until you hear a solid click. The ambidextrous thumb safety must then be disengaged before firing. Each shot is followed by a consistent recoil impulse, giving the shooter a tangible sense of each discharge. With an overall length of 225 mm and a weight of approximately 680 g, the MARK IV-M offers a stable shooting platform while remaining compact enough for easy transport.

For shooters seeking versatility, the MARK IV-M Silver includes a 11 mm dovetail rail on top of the receiver for optional scope or red-dot attachments. Whether plinking tin cans, zeroing in on paper targets, or dispatching small pests, the Umarex MARK IV-M Silver combines precision, reliability, and classic styling in a durable pellet pistol.
