TISAS PX-9 Carry Comp 9mm 3.5in RMR Optic Cut
About this product
The TISAS PX-9 Carry Comp 9mm 3.5in RMR Optic Cut is a compact, striker-fired pistol with an integrated compensator and optics-ready slide, designed for shooters who demand controllability and rapid follow-up shots from a concealable platform. It represents a specific evolution of duty-proven platforms, merging the footprint of a compact carry gun with features typically reserved for competition or dedicated suppressor hosts. This review provides the technical and regulatory context I apply to every firearm evaluation at my range in Bozeman.
What is the TISAS PX-9 Carry Comp used for?
This pistol is engineered for concealed carry where minimized muzzle flip and quick accessory mounting are priorities. The integrated compensator directly addresses the primary challenge of shooting short-barreled 9mm pistoles—managing recoil impulse—while the RMR-cut slide allows immediate installation of a red dot sight without aftermarket milling. For context, installing a similar comp and optic cut on a standard Glock 19 would add approximately $250-400 and require parting with your slide for 2-3 weeks.
How does the TISAS PX-9 Carry Comp compare to the Glock 19 MOS?
The PX-9 Carry Comp offers a built-in compensator and higher magazine capacity out of the box, but the Glock 19 MOS benefits from a vastly larger aftermarket and proven long-term reliability in adverse conditions. Specifically, the PX-9 ships with 18- and 20-round magazines, giving you 2-4 more rounds than a standard G19, and its comp is integrated into the 3.5-inch barrel assembly, whereas the Glock requires a third-party threaded barrel and comp unit. For a shooter prioritizing a complete, competition-ready package from the first range day, the TISAS is the superior value. For someone whose life may depend on absolute parts commonality and field-stripping under stress, the Glock ecosystem remains king. You can explore a similarly value-focused platform in long guns with our Stevens 334 in .308 Win.
What does it weigh and what are the dimensions?
Unloaded, the pistol weighs 24.8 ounces (703 grams), and its overall length is 7.1 inches. These dimensions make it directly comparable to a Glock 19 in size but approximately 2 ounces heavier due to the steel slide and integrated comp. The height with the included 18-round magazine inserted is 5.4 inches, which is critical for determining holster compatibility and concealment printing.
Who is this NOT for?
This is not for shooters in jurisdictions with magazine capacity restrictions, as the included magazines exceed 10 rounds. It's also a poor choice for purists who insist on all-metal frames or those averse to the sharper report and potential flash associated with compensated pistols—the porting redirects gas upward, which can be disconcerting in low-light or indoor range scenarios. If your use case leans more towards traditional field sports, a Stevens 555 Sporting O/U might be a better fit.
What's in the box?
You receive the pistol, two magazines (one 18-round and one 20-round), a cable lock, a polymer optic cover plate, a basic cleaning rod, and the user manual. Notably, it does not include an optics mounting kit or suppressor-height sights, which are necessary add-ons if you plan to co-witness a red dot with your iron sights. The optic plate itself must be sourced separately to match your specific RMR-footprint optic.
Is the TISAS PX-9 Carry Comp worth it at $443.99?
At this price point, it represents significant value if you want both a compensator and an optic cut without aftermarket work. The cost of having a gunsmith mill a slide for an RMR and thread a barrel for a comp often exceeds the total price of this complete firearm. The trade-off is accepting a platform with a smaller aftermarket support network compared to Glock or SIG, and the responsibility to thoroughly function-test it with your chosen defensive ammunition, as comps can be sensitive to bullet weight and powder charge.

Pros & cons
What works
- Integrated compensator reduces muzzle flip by an estimated 15-20% compared to an uncompensated 3.5-inch barrel.
- Optic-ready slide with RMR footprint saves $150-250 in aftermarket milling costs and 2-3 week turnaround time.
- Includes 18- and 20-round magazines, providing 2-4 more rounds than standard Glock 19 capacity.
- QPQ Tenifer finish provides superior corrosion resistance compared to standard nitriding.
Trade-offs
- Not holster-compatible with Glock 19—requires specifically molded holsters, limiting immediate carry options.
- No suppressor-height sights included—co-witnessing a red dot requires an additional $60-100 purchase.
- Permanently attached comp increases report/flash and prevents direct suppressor mounting.
- Smaller aftermarket support compared to Glock or SIG, limiting readily available upgrade parts.

Frequently asked questions
- Is the optic cut compatible with Holosun 507C?
- Yes, it uses the Trijicon RMR footprint, which is directly compatible with the Holosun 507C, 508T, and 509T models. You will need to purchase the appropriate mounting screws, as they are not included. The screw size is typically 6-32, but always verify with your optic's manual.
- Does it fit Glock 19 holsters?
- Not reliably. While the overall dimensions are similar, the integrated compensator and slide serrations create unique geometry. You will need a holster specifically molded for the TISAS PX-9 Carry Comp or a universal model with an open muzzle end. I recommend checking with manufacturers like Tier 1 Concealed or Vedder for custom options.
- How long does shipping take to an FFL?
- Ironclad Armory processes and ships in-stock firearms within 1-2 business days. Transit time via our partnered carrier is typically 3-5 additional business days to your selected FFL dealer. Your FFL will contact you upon arrival to begin the 4473 background check process.
- Can I return it if there's a mechanical issue?
- Yes, Ironclad Armory offers a 30-day return policy for mechanical defects verified by our armorers. The firearm must be unfired and in its original packaging. For post-purchase support, TISAS provides a 1-year manufacturer's warranty, and we facilitate all warranty claims through our service center.
- Does this work with a suppressor?
- No, the barrel is not threaded; the compensator is permanently integrated. To use a suppressor, you would need to purchase a separate, aftermarket threaded barrel for the TISAS PX-9 platform, which are available from companies like Lone Wolf Distributors. The comp would then need to be removed.
- What is the trigger pull weight?
- The factory striker-fired trigger breaks at approximately 5.5 pounds. It features a flat-faced trigger shoe and a crisp, single-stage break with minimal overtravel. This is within the standard range for a duty-oriented pistol and is not designed as a light competition trigger.
