SIG Sauer P320 320F9B Complete Specs and Full Gun Specifications

The P320 is a modular, polymer-framed service pistol designed from the ground up with the input of law enforcement officers. Featuring a serialized, stainless steel frame with a polymer grip module and a removable fire control assembly pioneered by Sig Sauer, the P320 is customizable to any hand size or duty requirement using interchangeable components (sold separately). The P320 does not require the operator to pull the trigger nor use a special tool to disassemble the firearm for cleaning or routine maintenance. With a partially pretensioned striker, it has a crisp trigger pull with a quick, pronounced reset. The P320 has no external safety or decocking lever to snag or hang up on the draw. It has an ambidextrous slide catch lever and a reversible magazine release for full ambidextrous operation. This model is chambered in 9mm with 17+1 capacity. It has a black finish.

Sig hit it out of the park with the full sized P320 9mm. Coming from a stock 2nd gen glock 19, I'm blown away by how great the trigger is. I am noticeably more accurate out to 25 yards with this pistol over my Glock. The longer barrel helps a bit, but I'm
