*Our compensators replace the barrel bushing. If you have a bull barrel or ramped barrel our compensators will not install.
Government Size 1911's have 5 inch barrels and full size frames. A Government 1911 requires full size grips. The barrel bushing is full size and will only accept full size compensators. A commander size compensator will not function properly on a Government 1911.
Commander Size 1911's have 4.25 inch barrels and full size frames. A Commander size 1911 requires full size grips. The barrel bushing is shorter than a full size Government model so you will need to purchase a Commander size compensator.
- Government/Commander grip measurements: The distance between the screw holes, center-to-center is 78 mm or approximately 3 1/16 inches.
Compact/Officer 1911's usually have barrel lengths around 4 inches or shorter. Only Officer/Compact grips will fit. We do not make compensators for this size because they usually do not have barrel bushings
- Compact/Officer grip Measurements: The distance between the screw holes is approximately 2 5/8 inches.
*Other barrel lengths and non-standard 1911's do exist. To find out if an item will fit your 1911 you can find the relevant measurements in the product descriptions.
A Bushing barrel has a barrel bushing. The barrel bushing's purpose is to support the front of the barrel in the slide and provide a bearing surface for the slide to traverse the barrel during the recoil cycle. Our 1911 compensators replace the barrel bushing.
A Bull Barrel or Ramped Barrel does not have a barrel bushing. Instead, the end of the barrel is thicker to provide the same function of a barrel bushing without needing the extra piece. If you have a bull barrel you will not be able to install a barrel bushing style compensator.
