Beretta APX Combat Threaded Barrel Features:

It has a serialized internal chassis that will accommodate external frames of various colors and sizes. Sporting full length, prominent slide serrations, an ambidextrous slide stop and a reversible magazine release this ergonomic self defense pistol can accommodate nearly any shooter. The trigger has a six pound pull with a short, very tactile and audible reset making it perfect for either training or everyday carry. 
The Beretta APX Combat takes this fantastic pistol to the next level with a factory slide cut to install some of today’s most popular Mini-Red Dot Optics and a threaded barrel for your suppressor! Four different optic plates allow you to easily install the Burris Fast Fire, Trijicon RMR, Leupold Delta Point or C-More optics. A blank plate is included so that you can still utilize the pistol without an optic installed. Suppressor Ready, it features a threaded barrel that is 1/2×28 TPI.
