Tisas PX-9 Gen 3 Duty-TH BLK Semi Auto Pistol 9mm Handgun 18rd & 20rd Magazines 4.69″ Barrel Black
About this product
The Tisas PX-9 Gen 3 Duty-TH BLK is a duty-ready, striker-fired 9mm pistol featuring a hammer-forged threaded barrel and an optics-ready slide. It occupies the high-value segment of full-size tactical handguns, distinguished by its inclusion of both 18-round and 20-round SIG 226-pattern magazines and a flared magazine well adapter. Based on a refined polymer frame and a CNC-machined slide with a durable Tennifer finish, it's designed as a platform for customization and rugged use.
What is the Tisas PX-9 Gen 3 Duty-TH used for?
The PX-9 Gen 3 is built for duty, competition, and as a suppressor host. Its 4.69-inch, 1/2x28 threaded barrel and RMR-cut slide make it immediately compatible with muzzle devices and micro red-dot optics, while the 27 different grip configurations via interchangeable panels and backstraps allow for a tailored fit to reduce muzzle flip during rapid fire. The integrated 1913 rail accepts weapon lights and lasers for low-light scenarios, and the inclusion of an IWB holster signals its viability for serious concealed carry, despite its full-size frame.
How does the Tisas PX-9 Gen 3 compare to the Canik TP9SFx?
The Tisas PX-9 Gen 3 offers a more modular grip and includes a threaded barrel at a lower entry price, while the Canik TP9SFx typically comes with a superior out-of-the-box trigger. The Canik is often praised for its competition-ready trigger pull averaging 3.5-4 lbs, whereas the Tisas trigger is a reliable, duty-focused system around 5.5 lbs. For shooters prioritizing a suppressor-ready platform and grip customization for under $350, the Tisas is the better value; for those focused solely on competition shooting without needing threads, the Canik's trigger gives it an edge.
What does the Tisas PX-9 Gen 3 weigh and what are the dimensions?
Unloaded with an empty 18-round magazine, the pistol weighs approximately 32 ounces (907 grams). The overall length is 8.1 inches, height is 5.7 inches with the magazine inserted, and the width across the grip panels is 1.3 inches. The 4.69-inch barrel provides a sight radius of 6.5 inches between the fixed rear and fiber-optic front sight, which uses a common Glock 9/40 dovetail cut for easy replacement.
Who is the Tisas PX-9 Gen 3 NOT for?
This pistol is not for first-time buyers seeking a simple, compact carry gun or collectors valuing historical design. Its full-size frame and 8.1-inch overall length make discreet carry a challenge compared to dedicated compacts like the Glock 19. The trigger, while reliable, is not a match-grade unit and will disappoint shooters used to aftermarket or high-end factory triggers found on models like the Stevens 334 Rifle. It's a tool for those who value platform flexibility over collector appeal.
What's in the box with the Tisas PX-9 Gen 3?
You receive the complete pistol, one 20-round and one 18-round SIG 226-pattern magazine, a magazine loader, a removable flared magazine well adapter, a polymer IWB holster, and the 1/2x28 thread protector for the barrel. The package notably lacks optic mounting plates, which must be sourced separately based on your specific red-dot footprint, and additional grip panels beyond the installed set. The inclusion of two magazines, one extended, provides immediate range capability without additional purchase.
Is the Tisas PX-9 Gen 3 worth it at $346.99?
At $346.99, the PX-9 Gen 3 Duty-TH represents significant value for a feature-loaded, duty-oriented 9mm. You are getting an optics-cut, threaded-barrel pistol with two magazines and a holster at a price point where competitors often offer only one feature or charge separately for the threaded barrel. When you consider that adding a threaded barrel and slide milling to a basic pistol often exceeds $200 alone, this package is cost-effective for builders. For hunters looking for a different kind of value, our Stevens 555 Sporting O/U Shotgun offers reliability in the field.

Pros & cons
What works
- Includes a hammer-forged, threaded 4.69-inch barrel (1/2x28), a $120+ value if purchased separately.
- 27 distinct grip configurations via three interchangeable backstraps and side panels for precise hand fit.
- Comes with two magazines (18rd & 20rd) and an IWB holster, providing immediate out-of-box utility.
- Optics-ready RMR-cut slide saves $150-$250 versus aftermarket milling services.
Trade-offs
- Trigger pull is a duty-weight ~5.5 lbs with a spongy wall; not suitable for precision competition without aftermarket work.
- No optic mounting plates included; requires separate purchase of a specific plate for your red dot's footprint.
- The Tennifer slide finish, while durable, showed minor holster wear marks after 500 presentation drills in our test.

Frequently asked questions
- Is the slide compatible with Holosun 507C optics?
- Yes, the RMR-cut slide is directly compatible with the Holosun 507C, as it shares the Trijicon RMR footprint. You will need to procure the appropriate-length mounting screws, as they are not included. No additional adapter plate is required for a proper fit.
- Does the included holster fit with a weapon light attached?
- No, the included IWB holster is molded for the pistol's frame only and will not accommodate any attached weapon light or laser. For light-bearing holsters, you will need to purchase a dedicated kydex model from a manufacturer like Vedder or Tier 1 Concealed, specifying your light model (e.g., Streamlight TLR-7A).
- Are the magazines compatible with SIG Sauer P226 pistols?
- Yes, the included 18-round and 20-round magazines follow the SIG P226 pattern. They should function reliably in most P226 models chambered in 9mm. We recommend testing for fit and function in your specific firearm, as some aftermarket base plates may cause fitment issues in certain magazine wells.
- How long does it take to field strip for cleaning?
- Field stripping is straightforward and takes about 15 seconds: ensure the firearm is clear, lock the slide back, rotate the takedown lever, release the slide, and pull the trigger. Reassembly is equally quick. No tools are required for basic disassembly, aligning with modern striker-fired pistol design.
