Key Features
- Threaded Steel Barrel (4.6 inches) — Why it matters: The threaded barrel lets you attach a compensator or suppressor without swapping parts, giving you more control over recoil and noise reduction for training or competition.
- Optics-Ready Serrated Slide — Why it matters: You can mount a red dot directly without milling, and the serrations give you a positive grip for press checks or one-handed slide manipulation under stress.
- Flared Magwell — Why it matters: The widened magazine well speeds up reloads by guiding the magazine home, even when you’re moving or under time pressure.
- Three 18-Round Magazines Included — Why it matters: You get 54 rounds total out of the box, reducing the need for extra magazine purchases and giving you extended range time without constant reloading.
- Flat Dark Earth Polymer Frame with Picatinny Rail — Why it matters: The FDE finish reduces glare in low-light conditions, and the integrated rail lets you mount lights or lasers for low-light shooting.
Who It’s For
This pistol is built for shooters who train regularly—whether you’re a new shooter stepping up to a duty-style handgun, a seasoned instructor running drills, or someone who wants a reliable home-defense option with modern features. The compact size balances concealability with a full grip, and the threaded barrel makes it adaptable for suppressor use or competition.
Pros & Cons
Pros: Excellent trigger out of the box, optics-ready without adapter plates, flared magwell for faster reloads, threaded barrel adds versatility, three high-capacity magazines included.
Cons: The slide is a bit wider than some competitors, which may affect holster compatibility for concealed carry. Also, the aggressive texture on the grip can wear on clothing over extended carry.

The Zev gives you a fully modular chassis, and the Agency Arms features a more refined slide cut, but the Walther delivers comparable performance for less money.
