I remember seeing adds several years back for a single shot barrel kit made by springfield armory to fit on the 1911 frame. As I remember it appeared to have a rotating breech.
Does anyone know what it is called? Is it still made? Are they available?

It was made by Pachmayer (sp) and was called the Dominator. I do not remember the caliber choice.

The Pachmyr unit was called the Deominator and came in a variety of calibers like 308..7-08..358 win and 35 Rem I believe. The Springfield unit was called the SASS I think. Calibers were in the similar range. Easy to install on your 1911 frame and quite accurate and easy to shoot.

Greetings! Neither the Springfield SASS or Pachmayr Dominator are still produced. One may find them occasionally on the used market. This is my 15" barreled 308 win Pachmayr Dominator, topped with a Burris 3-12 in Leupold QRW rings, with laminate wrap around fingergroove thumbrest grips on a Kimber frame. This setup easily groups under an inch at 100 yards from the bench, and near that from my rested field positions.

It is pretty simple in design. It uses a 3-lug bolt that you turn with a small bolt handle on the rear of the action, with a bolt face that is very much like a shell holder. The large wedge of steel in the front of the action acts as an accurizing adjustment wedge between the frame and the barrel. For a tight fit, you spred the wedge further apart until there is firm pressure on the underside of the barrel when assembled. This way, the system works on a variety of 1911 actions with all of their manifest tolerance differences.

When I shoot it rested and do not have time to set up a proper bench rest with sandbags, I often use the Millett pistol rest in the pic, and rest it just as shown, adjusting for elevation with the elevation wedge in the rear of the rest.
