[1][2] Sauer 90 and 92 were later and updated models only sold in Europe, with the main changes being related to the trigger guard and stock.

[1] The rifle is known for having very good precision, and has been used by hunters and sport shooters, and also in a sniper version known as SIG Sauer SSG 2000 by police and defense forces.

The safety is conveniently placed on the tang of the stock, but little wood in this area makes it a weak spot which is known for breaking if the rifle falls.

The rifle is also known for being difficult to glass bed due to the shapes of the recoil lug and barrel nut, as well as ensuring that the magazine is seated correctly.

Rear locking ensures a shorter bolt travel, but also makes the brass case (as well as the receiver, but with modern metallurgy it's strong enough to not influence anything) stretch considerably more during firing.

[8] Due to the rear locking lugs, the precision of the rifle is also known to be very sensitive to oil or water entering the chamber, even more so than the Krag–Jørgensen.

[citation needed] The Sauer 80/90/92's and the Lux variant of CG 3000 have an empty chamber bolt hold open mechanism and a steel bottom metal.

The standard edition of CG 3000 has an aluminium bottom metal and lacks an empty chamber bolt hold open.
