All three are optics ready Beretta 92 series 9mm pistols using the same dovetail and plate mounting system. The M9A4 is the duty pistol with a threaded barrel and decocker. The 92X RDO is the practical version with a rail and a selectable safety or decocker. The 92X Performance Defensive is the heavy steel competition gun with an adjustable trigger.
This was launch news, and we did not test these guns for this article. Here is how Beretta’s announced specs compare.
Beretta just announced the updated M9A4 service and duty pistol for self-defense, and is following it up with two new optics-ready 92X pistols. They are the new 92X RDO Full Size and 92X Performance Defensive, both chambered for 9mm Luger.
These 90-series pistols use the same red-dot-optics mounting system Beretta selected for the M9A4, which uses a set of dovetails in the slide to mount adapter plates. Because the dovetails can mount pretty much any kind of adapter, the system can accommodate a wide range of mini red dot sights.
Of the two models, the 92X RDO is the more practical-tactical pistol, while the 92X Performance Defensive is more range- and competition-oriented. In fact, the Performance Defensive pistol was specifically tailored to compete in prominent shooting sports, and specifically IDPA games.
Both are fully featured double-action, single-action handguns that come with Beretta’s Vertec-pattern frame. The reduced radius of the grip and thin grip panels make handling these pistols easier for a wide variety of shooters and hand sizes.
The 92X RDO has a light alloy grip with a full-length accessory rail, a universal pattern slide with a safety-decocker lever or a decocker-only lever and forward and rear slide serrations. The RDO comes standard with a high visibility orange dot front sight with black combat rear sights
Because it’s a universal slide, the lever can be switched from safety-decocker to decocker-only and vice-versa. Standard-capacity with the RDO is 18+1 rounds although 10- and 15-round magazine packages are also offered.
The 92X Performance Defensive is an all-stainless steel design with a lightened frame and slide to meet common competition weight requirements. While the RDO weighs a bit over 33 ounces unloaded, the Performance Defensive weighs 42.7 ounces.
The added weight helps with felt recoil and a fast return on the sights for quick, flat shooting. The Performance Defensive does not come with a safety rail or a decocker, instead, it has a traditional frame with ambidextrous manual safety levers.
Another difference between the two models is the barrel length. While the RDO has a standard 4.7-inch barrel, the Performance Defensive has a slightly extended 4.9-inch barrel, which gives it a slight advantage in muzzle velocities for shooting sports that have specific ammunition performance requirements.

I’d avoid Beretta products at most all cost. I sent my pistol back to them for warranty work way back in 11/2020. Still waiting for parts and the customer service reps could not care less. AVOID Beretta
