Glock G45 Gen5 9mm vs Smith & Wesson M&P 9 M2.0 Full Size OR 9mm

Both hold 17 rounds of 9mm and sit within 0.04" of each other in overall length (7.44" vs 7.4"). The meaningful differences are weight, trigger and optic provision: the Smith & Wesson M&P 9 M2.0 Full Size OR 9mm is 4.52 oz heavier (29.0 oz vs 24.48 oz), lists a 1.3 lb lighter trigger pull (4.5 lb vs 5.8 lb), is optic-ready where the Glock G45 Gen5 9mm is not, runs a 0.23" longer barrel (4.25" vs 4.02") and a 0.48" longer sight radius (6.5" vs 6.02"), and is 0.18" narrower (1.16" vs 1.34"). MSRP is $52.00 apart ($699.00 vs $647.00), and the Glock includes three magazines to the M&P's two.

Pick the Glock G45 Gen5 if:

• You want the lighter gun on the belt, 24.48 oz against 29.0 oz
• The 5.47" height and 7.44" length suit how you carry 17 rounds
• Three magazines in the box, at $647.00

Pick the Smith & Wesson M&P 9 M2.0 Full Size OR if:

• You want the 4.5 lb factory trigger rather than 5.8 lb
• You are mounting a red dot and want the optic cut from the factory
• Four interchangeable palmswell inserts and a 1.16" width fit your hand better

Capacity and length are a tie, so it comes down to fit and features. The M&P brings a 1.3 lb lighter trigger, an optic cut and adjustable palmswells for 4.52 oz more weight and $52.00; the G45 stays lighter and ships with an extra magazine.
