Glock G20 Gen5 MOS 10mm vs Smith & Wesson M&P M2.0 10mm

These two polymer 10mms share 15+1 capacity, 4.6" barrels, optic-ready slides, and weights within 1 oz of each other (G20 28.4 oz, M&P 29.3 oz). The two meaningful differences are the trigger and the manual safety. The Smith & Wesson M&P M2.0 breaks at 4.3 lb — 1.6 lb lighter than the G20 Gen5 MOS's 5.9 lb pull, the largest stock trigger-weight gap among polymer 10mms — and is the only factory polymer 10mm offered with a frame-mounted thumb safety. The Glock ships with three magazines to the M&P's two, and has the largest 10mm aftermarket of any platform on the market.

Pick the Glock G20 Gen5 MOS if:

• You want the deepest 10mm aftermarket for holsters, replacement barrels (including .40 S&W and 6" hunting conversions), and chest rigs — no other 10mm comes close
• You want three included magazines versus two with the M&P, and the option to use Glock G40 mags interchangeably for shared-magazine hunting setups
• You want the longer 34-year track record with hot factory loads from Underwood, Buffalo Bore, and DoubleTap, which the M&P 10mm does not have at the same volume

Pick the Smith & Wesson M&P M2.0 if:

• You want the 4.3 lb flat-face trigger — 1.6 lb lighter than the Glock's stock 5.9 lb pull, with a cleaner break that owners consistently rate above factory Glock triggers
• You want a frame-mounted manual thumb safety on a 10mm — no factory G20 ships with one, and many woods-carry shooters specifically want an external safety on a chambered hot round
• You want four interchangeable palmswell inserts that change grip circumference, not just the Glock backstrap system's profile change

Both run polymer frames with steel slides, both are factory optic-ready, both carry 15+1, and both share Picatinny rails for weapon lights. The choice rides on trigger pull weight and manual safety preference versus magazine count and aftermarket depth.
