## Description

The P320 RXP Compact is a striker-fired 9mm that ships with a ROMEO1 PRO Reflex Optic already mounted, no separate optic purchase needed. The modular P320 platform means you can swap grip modules in small, medium, or large to dial in the fit.

### Key Specifications
- **Model:** P320 RXP Compact
- **Caliber:** 9mm Luger (9x19 Para)
- **Action:** Striker-Fired Semi-Auto
- **Capacity:** 15 rounds
- **Barrel Length:** 3.9 inches
- **Weight:** 1.5 lbs.
- **Finish:** Two-tone black and stainless

### Detailed Features
- **ROMEO1 PRO Reflex Optic with Suppressor Contrast Sights:** The optic is installed at the factory alongside tall suppressor-height contrast sights, so the irons remain usable whether the optic is on or not.
- **Serialized Striker-Fired Trigger Group:** The trigger group is a discrete serialized unit. It can be moved to a different P320 grip module without going through an FFL transfer.
- **Modular Polymer Grips in Small, Medium, and Large:** The interchangeable grips let you match the frame to your hand without aftermarket work.
- **3-Point Takedown System:** Field-stripping does not require pulling the trigger, which reduces the handling risk during disassembly.
- **Ambidextrous Slide Catch Lever and Reversible Magazine Catch:** Both controls work for left- and right-handed shooters out of the box.

The 3.9-inch barrel and 1.5 lb. weight keep this in compact territory, suitable for concealed carry and equally functional on the range or in a duty role.

## What Customers Say

*AI-generated insights from customer reviews*

P320 RXP Compact owners tend to focus on a few consistent topics.

The modular design is well-liked. Being able to swap grip sizes and, in principle, move the serialized fire control unit to a different frame is something P320 owners actively use. The compact form factor suits both carry and home defense.

The factory-installed ROMEO1 Pro is the most discussed feature. Most users find the red dot meaningfully faster for target acquisition, particularly in dynamic or low-light conditions. That said, there's a learning curve for anyone transitioning from irons only, and a portion of users raise questions about long-term optic durability and battery life.

Overall the reception is positive, with the optic integration and platform modularity being the main selling points.
