[Umarex] S&W M&P40 Pistol - Second Hand

The Umarex S&W M&P40 is a realistic CO2-powered air pistol that's licensed by Smith & Wesson, replicating the look and feel of the popular M&P40 duty handgun used by law enforcement and civilians.

It's chambered for .177 caliber (4.5mm) steel BBs, making it ideal for plinking, target practice, or as a training tool for those familiar with the real firearm.umarex.com

This non-blowback model features a semi-automatic action with a full-metal slide that cycles realistically on each shot, powered by a single 12g CO2 cartridge inserted into the grip. It has an 18 round drop-free magazine (depending on the specific variant), fiber optic sights for quick target acquisition, a manual safety, and a double-action trigger pull that's smooth and consistent.

The construction mixes metal and polymer for durability and authenticity, weighing about 1.61 lbs (730g) with a 3.5-inch smoothbore barrel. Velocity typically ranges from 300-410 FPS, offering decent power for backyard shooting while keeping things safe and affordable—expect around 50-70 shots per CO2 cartridge before velocity drops.It handles really nicely, with ergonomic grips that fit well in the hand, good balance for one-handed or two-handed shooting, and controls that mimic the original firearm for intuitive operation.

Users often praise its realism and reliability. For maintenance, just lubricate the seals occasionally with silicone oil. In the UK, it's available from retailers for around £130-£170 new, and it's legal for adults without a license as long as it's under 6 ft-lbs energy (which this is).
