Stoeger STR-45 Combat
The Stoeger STR-45 Combat is a 2026 full-size .45 ACP striker-fired pistol that debuted at NRAAM 2026 as one of the most capable factory-ready suppressor hosts in its caliber. With a 5.18-inch threaded barrel, suppressor-height fiber-optic sights, optics-ready slide with four mounting plates included, and 16+1 capacity, the STR-45 delivers a complete duty and suppressor-ready package at a $649 MSRP that undercuts most competitors significantly.

STR-45 Combat: What You Get for $649
At $649 MSRP the STR-45 Combat ships with three magazines, four optic mounting plates covering the most common red dot footprints, suppressor-height fiber-optic front sight with adjustable rear, and a factory-threaded .578×28 TPI barrel ready for a .45 ACP suppressor. Most .45 ACP pistols at this price point ship with one magazine, no optic plates, and standard-height sights that become unusable with a suppressor mounted. The STR-45 Combat’s out-of-box configuration is genuinely suppressor-ready without additional purchases.

STR-45 vs Glock 21: Full-Size .45 ACP Compared
The STR-45 Combat and Glock 21 are both full-size .45 ACP pistols with double-stack magazines, but they approach the market very differently. The Glock 21 carries 13+1 in a proven, broadly supported platform with decades of holster and accessory availability. The STR-45 Combat exceeds that with 16+1 and ships suppressor-ready with optic plates at a lower price point. For buyers who want maximum .45 ACP capacity with factory suppressor capability, the STR-45 Combat wins decisively on features per dollar. For buyers who prioritize the Glock ecosystem and long-term accessory support, the G21 remains the standard.
Why .45 ACP for Suppressed Use?
.45 ACP is one of the best calibers for suppressed pistol use because standard pressure loads are already subsonic — the 230-grain FMJ travels at approximately 830 ft/s, well below the 1,125 ft/s speed of sound. This means no supersonic crack when fired through a suppressor, producing significantly lower overall sound levels compared to supersonic 9mm loads through the same can. The STR-45 Combat’s .578×28 TPI threaded barrel accepts most .45 ACP pistol suppressors. Visit our suppressors page for compatible cans.
