The Sig Sauer P320 Compact is a compact striker-fired 9mm built for duty and concealed carry. Sig still builds it, and the serialized part of it is a stainless steel fire control unit that lifts out of the grip module, so the polymer around the trigger group is a component and not the registered firearm.

Two 15-round steel magazines come in the box. The grip module is a compact medium in black polymer with an M1913 rail moulded under the dust cover, so a standard weapon light clamps straight on with no proprietary adapter. The barrel is carbon steel with a DLC coating. The trigger is the plain curved P320 unit, and this version has no manual safety, although Sig fits one to certain P320 models.

If you're cross-shopping, the Sig Sauer P320 XCarry runs the same barrel length and weighs 26.5 oz, 0.1 oz under the Compact, but its X-Series module holds two more rounds and adds an extended beavertail, which takes it to 7.4 inches overall against the Compact's 7.25. The Glock G19 Gen5 matches the Compact's count at 23.63 oz, 2.97 oz lighter, on a 4.02-inch barrel, and its slide has no optic cut, so a dot on one means a machined slide.
