SIG Air x SIG Sauer ProForce M17 GBB Pistol in Desert Tan

When it comes to faithful sidearm replicas, few airsoft pistols match the authenticity of the SIG Air x SIG Sauer ProForce M17. This is more than just a GBB pistol—it’s a fully licensed 1:1 replica of the U.S. Army’s M17, based on the SIG P320 platform. From the moment you draw it, everything from the weight to the balance screams realism. In its desert tan finish, it not only looks field-ready but plays the part with serious performance under the hood.

At its core, the M17 is built for flexibility. You’re not locked into one propellant type—this pistol is dual-system compatible, meaning you can run it on standard Green Gas or switch to CO₂ by simply swapping the magazine. That’s a godsend when the temperature dips or you just want that extra bit of kick from CO₂. Either way, you’re getting reliable cycling and excellent gas efficiency, thanks to its well-tuned internals and solid slide construction.

The externals are just as impressive. You’ve got a metal slide that feels satisfyingly hefty during blowback, mounted on a durable aluminium alloy and fibre-reinforced polymer frame. The result is a sidearm that feels tough in hand but won’t slow you down on the move. The ergonomics are spot-on, too—SIG didn’t cut corners. From the grip angle to the trigger geometry, this pistol feels like a service weapon, not a toy.

Let’s talk optics. This M17 comes optic-ready right out of the box. The slide includes a removable rear sight plate, making it a breeze to mount your favourite micro red-dot or reflex sight without needing extra adapters. It also features a built-in Picatinny accessory rail under the muzzle, so fitting a torch or laser is no hassle—perfect for CQB or low-light games.

Performance-wise, you’re looking at a muzzle velocity of around 320–350 fps with 0.20g BBs. That’s ideal for skirmish fields across the UK—strong enough to make your hits count, but still compliant with site limits. Add in the adjustable hop-up and you’ve got fine-tuned control over your BB trajectory, helping you stretch those shots or dial in for tighter CQB engagements.

The ProForce M17 ships with a 25-round gas magazine, which is plenty for sidearm work. The realistic gas blowback gives you that satisfying snap with each shot—recoil you can feel in your hand and hear with each cycle. It’s the kind of immersive feedback that really makes a difference when you’re under pressure.

This is the sort of pistol you want to carry when your primary goes down, or when you need a serious backup that won’t let you down. Whether you’re using it in a milsim scenario or just looking for a sidearm with some serious bite, the M17 in tan delivers the goods.
