SIG Sauer Hand Pump HP4500

SIG Sauer Hand Pump HP4500

Experience the ultimate in field-ready air supply with the SIG SAUER HAND PUMP HP4500. Built by a legendary ISO 9001-certified manufacturer in Newington, New Hampshire, this three-stage stirrup pump brings SIG SAUER’s precision engineering to every fill. Whether you’re gearing up for a dawn competition, tightening your stance in a backyard plinking session, or preparing for critical pest-control work, the HP4500 puts fast, reliable high-pressure air right at your fingertips.

Crafted from aircraft-grade aluminum and hardened steel components, the HP4500 delivers up to 4,500 PSI (310 bar) of pure, dry air without a single electrical outlet or bulky compressor. Its three-stage piston design eases your workload by gradually building pressure through each stroke, so you get maximum output with minimal effort. A reinforced folding step plate and nonslip rubber base pads lock the pump in place on uneven terrain, letting you plant your foot firmly and pump with confidence—even on gravel, grass, or slick surfaces.

Connecting to 1/8″ BSP (8 mm) fittings, this hand pump is engineered to work seamlessly with most PCP air guns, including the Sig Sauer Virtus 5.5 mm. A precision-machined hose swivel makes attaching and detaching your fill whip effortless, while an integrated pressure gauge gives you clear, instant feedback so you can stop pumping at exactly the right moment. Compact enough to stow in a gear bag or rifle case yet rugged enough to withstand years of heavy use, the HP4500 is the go-anywhere solution for shooters who demand autonomy and accuracy.

Backed by Sig Sauer’s world-class firearms heritage, the HP4500 is more than just a hand pump—it’s a testament to relentless quality, peak performance, and the confidence that only the best gear can deliver. Elevate your shooting routine with the pump that refuses to let you down, whether you’re in the field, on the range, or out at the ranch.
