S&W M&P22 Compact | 108390 | .22 LR | 3.56″

The Smith & Wesson M&P22 Compact (MFG# 108390) is a reduced-scale compact pistol built around a polymer frame with integral Picatinny-style rail and an anodized aluminum slide. It is chambered for .22 LR and supplied with two removable magazines; the design mirrors the ergonomics and controls of full-size M&P pistols for training and target work. A compact red-dot such as the Vortex Venom (3 MOA) pairs well with this platform for fast, accurate sight acquisition while remaining well under $1,000.
