Description
The Tisas PX-9 Gen 3 Duty-TH is a striker-fired 9mm built for shooters who want a lot of capability without the premium price tag. The "TH" tells you the important part: a 4.69-inch hammer-forged barrel finished with 1/2×28 threads and a protector, so it's ready for a suppressor or compensator straight out of the box. The frame is black polymer with an integrated M1913 Picatinny rail up front for a light or laser, and the CNC-machined slide wears a tough black Tennifer finish with front and rear serrations for solid purchase.
This pistol runs on SIG P226-pattern magazines, and it ships with one 20-round and one 18-round mag, giving you nearly 40 rounds on tap between the two. That higher capacity makes it a natural fit for duty, home defense, or a fun day at the range. The slide comes cut for the Trijicon RMR footprint with a cover plate installed, and the green fiber-optic front sight paired with a drift-adjustable rear gives you a fast, clean sight picture whether or not you add a red dot.
One of the standout features is the grip. With three interchangeable side panels per side and three backstraps, you get 27 different configurations to dial in the fit, which is rare at this price point. Add in textured index points for your thumb and trigger finger, a flat-faced trigger with an integrated trigger safety, a reversible mag catch for lefties, and a flared mag well for faster reloads, and you've got a pistol that punches well above its weight.
Reviewers and owners consistently call it out as one of the best bang-for-the-buck striker guns on the market, with a trigger that gets compared to far more expensive pistols. It's a bigger gun in the spirit of a full-size duty pistol, so it shines as a range, home-defense, or nightstand gun rather than a deep-concealment piece. The package includes a lockable hard case, IWB holster, magazine loader, cleaning kit, spare fiber-optic rods, owner's manual, and the full grip kit.

Frequently Asked Questions
What does the "TH" in PX-9 Gen 3 Duty-TH mean?
TH stands for threaded, referring to the 4.69-inch barrel cut with 1/2×28 threads. That lets you mount a suppressor or compensator, and a thread protector comes installed for when you're running it bare. It's the same proven Duty platform with the suppressor-ready barrel added.
Is the slide ready for a red dot optic?
Yes. The slide is cut for the Trijicon RMR footprint and ships with a cover plate in place. The included green fiber-optic front and adjustable rear sights are tall enough to give you a lower-third co-witness through many optics, so you can run irons, a dot, or both.
What magazines does the PX-9 Gen 3 Duty use?
It uses SIG P226-pattern magazines, which is great for availability and spares. This model ships with one 20-round and one 18-round magazine, both proven and reliable. Quality aftermarket P226 mags will generally work as well.
Is this a good pistol for concealed carry?
It can be carried, but it's built on a full-size, duty-style frame closer to a Glock 17 or XD-M, so it's not a deep-concealment gun. It really shines as a home-defense, nightstand, or range pistol where capacity and shootability matter most. If you want something smaller for everyday carry, the PX-9 Carry is the better fit.
How is the trigger on the PX-9 Gen 3 Duty?
The flat-faced trigger is one of the most praised features on this pistol, with owners frequently comparing it to triggers on guns costing much more. It includes an integrated trigger safety and breaks clean for a striker-fired pistol in this price range. It's a big part of why the PX-9 has such a strong value reputation.
