Key Features
- Threaded Barrel (1/2×28): Why it matters — lets you run a suppressor or compensator without needing a gunsmith, making it ideal for quiet hunting or reduced recoil at the range.
- Performance Duty Trigger: Why it matters — gives you a crisp, consistent 4.5-pound pull that helps you stay on target during fast follow-up shots, just like a tuned 1911.
- Optics-Ready Slide: Why it matters — accepts over 100 different red-dot footprints (including Trijicon RMR and Leupold DeltaPoint Pro) so you can mount your favorite dot without extra plates.
- Ambidextrous Slide Stop and Magazine Release: Why it matters — works for lefties and righties alike, making it a true universal tool for any shooter.
- 10-Round Magazine (Compliant States): Why it matters — keeps you legal in capacity-restricted states while still giving you enough firepower for self-defense or competition.
Who It’s For
This pistol is for the southern gentleman shooter who appreciates a reliable, accurate handgun for home defense, range days, or running a suppressor on a dove hunt. It’s also a fine choice for the competition shooter who wants a full-size 9mm with a threaded barrel and factory-ready trigger.
Pros and Cons
- Pros: Excellent trigger, threaded barrel included, optics-ready slide, ambidextrous controls, reliable Walther quality.
- Cons: The 10-round magazine may feel limiting for shooters in free states who prefer 15- or 18-round options. Aftermarket support is growing but not as deep as Glock’s.
