SHOT Show 2018: Windham Weaponry .450 Thumper Pistol

Have you been feeling a little blue because you haven't been able to find a semi-automatic handgun chambered for straight-walled, big-bore cartridges like the .450 Bushmaster? Well, cheer up friend! Windham Weaponry has just what you're looking for.

The new .450 Thumper pistol (RP9SFS-450M) features a forged 7075 T6 aircraft aluminum flat-top upper receiver paired with a Magpul enhanced trigger guard lower receiver, both of which are treated with a hardcoat black anodize finish. The 9” long medium-profile barrel is made of 4150 chrome-moly steel, sports a Melonite QPQ finish and has an M4-style feed ramp. The threaded muzzle is fitted with a much needed 3-chamber muzzle brake to tame felt recoil. The 7" long free float 6063 aluminum handguard has M-LOK accessory and QD sling attachment points. The end plate features a QD socket with a sling swivel provided.

This gun ships with a set of Kriss polymer flip-up sights. The smooth, pistol-style buffer tube is fitted with an SB Tactical wrist brace. Other features include a Hogue over-molded pistol grip, one five-round magazine and a hard side storage case. Suggested retail for the .450 Thumper is $1,254.
