Hi Victor and welcome.
Beretta USA PX4 G-SD Features
This model operates with a DA/SA action, allowing for a smooth and consistent trigger pull in every shot. The black Bruniton slide is not only aesthetically pleasing but also provides a layer of protection against corrosion and wear. It is complemented by a serrated slide for improved grip during slide manipulation. The frame is constructed from polymer and includes a Picatinny rail for easy attachment of accessories such as lights and lasers.
The PX4 G-SD is designed with ergonomics in mind, featuring a full-size polymer frame that provides a comfortable and secure grip. The high-viz orange front sight and black rear sight configuration ensure quick and accurate target acquisition. Safety is a priority, with a decocker to safely lower the hammer without discharging the firearm. 2-17 rd. and 1-21 rd magazine included. Cheers, stay safe and enjoy!
