Stoeger's Slimmer STR-9 Thinline Keeps Its 16-Round Capacity

October 18, 2026

Stoeger has taken its STR-9 striker-fired pistol and put it on a diet, trimming it down to a 1.08-inch width without cutting into magazine capacity. American Rifleman got hands-on time with the new STR-9 Thinline and came away with a solid review of a carry gun that doesn't try to reinvent the wheel.

Key points

  • Capacity: The Thinline holds 16+1 rounds and ships with two spare mags at 14 rounds each, so slimming the grip didn't cost much ammo on board, according to American Rifleman.
  • Grip texture: A mix of checkering, fine stippling and a subtle single-finger groove on the frontstrap combine with an undercut trigger guard for a secure, comfortable hold, the review notes.
  • Optics-ready slide: The slide is cut for the popular RMSc footprint and comes with a cover plate for shooters sticking with the tritium night sights.
  • Slide manipulation: Widened "ears" at the rear of the slide, similar to an H&K VP9, help with racking, though the reviewer found the slide release itself small and tough to run quickly.
  • Range performance: Testing at 7 yards with Hornady, Black Hills and Winchester 9mm loads produced no malfunctions and reasonable defensive accuracy, per the review.

Quick take

American Rifleman's takeaway is that Stoeger didn't overthink this one—it built a concealable 9mm with useful features like a removable mag well, ported barrel and night sights, then priced it under $600. For anyone shopping the crowded carry-gun market, that combination of size, capacity and price is worth a look.
