Detailed Features

• The slide is cut for a red dot optic with an RMR mounting footprint and has front and rear serrations for manual racking. 
• A fiber optic front sight pairs with the optic-ready slide for fast target pickup with or without a red dot mounted. 
• The grip has interchangeable backstraps and side panels, along with a Picatinny rail under the dust cover for a light or laser. 
• Two magazines, one 18-round and one 20-round, come standard, giving the pistol a 20+1 capacity in its highest configuration.

Owners of the PX-9 generally report it runs reliably once broken in, and many credit the cold hammer forged barrel and Cerakote finish for holding up to regular range use. Some new owners mention wiping down factory-applied lubrication or a few sharp edges before their first range trip, a common note among value-priced striker-fired pistols in this class.

The grip's interchangeable backstraps and side panels let most shooters land a comfortable fit, and the RMR-cut slide makes adding a red dot straightforward. A few owners feel the factory trigger has more takeup than duty-grade pistols at a higher price point, though many say it's workable for range and home-defense use as it comes from the factory.

The PX-9 Gen 3 Tactical draws praise for undercutting name-brand striker-fired pistols while still including a threaded barrel and optic-ready slide as standard. Holster and accessory fit vary by maker since the PX-9's dimensions track a well-known polymer pistol pattern, so buyers usually check compatibility before ordering.
