The SIG SAUER P320 is a modular designed series of striker fired pistols. The stainless steel frame (pictured above) is the serialized part for BATFE purposes. Once you have the stainless steel frame, it can be put into a Full Size, Carry, Compact, or Sub Compact frame each with a Large, Medium, or Small Grip. All of the combinations can be chambered in 9x19mm, .357 SIG, or .40 Smith & Wesson.

The safety mechanisms include a striker safety that prevents the striker from releasing unless the trigger is pulled, a disconnect safety that prevents the pistol from firing when out of battery, a tabbed trigger safety, and a magazine disconnect safety. Also, to take the gun apart you must remove the magazine, lock the slide to the rear, and rotate the take-down lever.
