Owners of the M&P 22X appreciate the full-size feel paired with the low cost of .22 LR ammunition, making range sessions longer without the usual expense. The threaded barrel and optics-ready cut are frequently cited as practical additions that most rimfire pistols in this class skip.

The trigger draws mixed reactions. Some find it crisp and consistent for a rimfire, while others wish it broke more cleanly than a typical M&P. Ergonomics get consistent praise, especially from shooters already familiar with the M&P platform.

Value is the recurring theme in owner feedback. The two included 20-round magazines and the Armornite finish are seen as genuine value adds. A few owners report occasional feeding hiccups with bulk-pack ammo, though premium .22 LR runs without issue for most.
