Western Arms SV Infinity Tactical 5.0 GBB Pistol (2026 Version)
 
This tactical custom build boasts the highest power and recoil of any Magna Blowback handgun, featuring a heavy-duty high-capacity design and a metal barrel block.
Boasting the strongest recoil and highest gas capacity in the Western Arms (WA) Magna Blowback lineup, this SVI Infinity 4.3" Tactical Custom combines a modular double-stack frame with a front-weighted metal barrel block. Weighing over 1 kilogram, it delivers massive blowback kick, superior cool-down resistance during rapid fire, and competition-grade ergonomics.
Maximum Recoil & Cold Resistance: Utilizes a large-capacity double-stack magazine with an enlarged internal gas reservoir, minimizing pressure drop in cold weather and powering a bored-out, long-stroke cylinder for top-class recoil shock.
4.3" Carbon Black HW Slide: Newly molded from high-density Carbon Black Heavy-Weight resin with a flat-top profile and six front cooling ports (three per side) for reduced reciprocating mass and an aggressive race look.
Metal Barrel Block & Bull Barrel: Features a full-metal extended dust cover subframe topped with a vented metal barrel block, revealing a cone-shaped aluminum bull barrel underneath for front-heavy balance and reduced muzzle rise.
Competition Sight Setup: Outfitted with a high-visibility fiber-optic front sight paired with a fully adjustable Bo-Mar style rear sight featuring white alignment dots for fast, precise target acquisition.
Modular Double-Stack Grip Frame: Rigid reinforced resin grip frame eliminates flexing and features double trigger-guard undercuts for a higher two-handed grip, a scalloped magazine release recess, and an integrated 20mm Picatinny rail for tactical lights.
Over 1kg Heavyweight Build: Combines the full-metal subframe, metal barrel block, and Carbon Black HW slide to exceed 1,000g in weight, providing a commanding, true-to-steel hand feel.
