The SD9 2.0's flat-face trigger breaks at 4.5 lbs with minimal take-up. That pull weight beats the Glock G17 Gen5 at 5.8 lbs, the Sig P320 at 6.5 lbs, and the S&W M&P M2.0 at 6.5 lbs. The 2018 update dropped the original SD9's trigger from 8 lbs to 4.5 lbs and added a flat trigger face, which transformed the gun from a forgettable entry-level pistol into something that outperforms its weight class on the one spec shooters feel most.

The trade-offs are real. The SD9 2.0 ships with one magazine instead of two. No optic-ready slide exists. The fixed white dot sights are basic. At 22.7 oz with 16 rounds and a 4-inch barrel, the package is lighter and slightly smaller than most full-size 9mms. The Ruger Security-9 competes in the same space with 15 rounds and a 4-inch barrel but runs a heavier 5.5 lb trigger. The SD9 2.0 is the gun that makes the most sense when the trigger matters more than the accessories list.
