Notes

SIG produced several Tac Ops sub-variants including a Carry model with a 4.25-inch barrel and a 10mm Auto version. The full-size threaded-barrel model (5.6-inch barrel with thread protector) was popular as a suppressor host. All SIG 1911s were manufactured at the Exeter, New Hampshire facility. The Tac Ops was consistently praised for its reliability, with reviewers reporting zero malfunctions across extensive testing with both ball and hollow-point ammunition.

Background

SIG Sauer entered the 1911 market in 2004 with the Granite Series Rail, bringing modern manufacturing precision to the century-old Browning design. The Tac Ops was considered among the finest service-grade 1911s ever built, combining the classic platform with contemporary tactical features like the Nitron finish, accessory rail, and night sights.
