1911 Size Guide: Will this fit my gun?

Government 1911's

(5 inch barrel)

Commander 1911's

(4.25 inch barrel)

Compact/Officer 1911's

(4 inch or shorter barrel)

Full Size Grips YES YES NO
Compact Grips NO NO YES
Full Size Compensators YES NO NO
Commander Compensators YES YES  NO

 *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 accept full size compensators as well as commander size compensators.  

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.


Barrel Types:

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. 



What is the Recessed Ambi Safety cut?/Do I need this cut?

The recessed ambi cut is a notch cut into the back side of the right grip panel.  It leaves clearance for an ambi safety leg some 1911's have which sits under the grip.  If you take off your stock grips and the back sides (that sit flush against the gun) are completely smooth then you do not need this cut.  If you do need this cut we will add it for no additional cost.  Just put "ambi cut" in the SPECIAL INSTRUCTIONS FOR SELLER box when you checkout.


 What are the most common fitment issues I may encounter when installing an after market compensator?

  • Some buyers may find that they need to modify the locking lug on the compensator if the fit is too tight.  If you are comfortable making modifications yourself you can usually do so with either a dremel or fine grit sandpaper.  If not we recommend consulting a gunsmith.
  • If your stock spring plug is longer than 1.2" it will most likely not depress down far enough to install the compensator.  In that case we recommend that you use a Valkyrie Dynamics spring plug, Commander spring plug, or shorten your stock spring plug.


Why do you recommend a Valkyrie Dynamics/ Commander spring plug to install the compensator?

We recommend our spring plug or a Commander spring plug because some Government 1911's have spring plugs that are too long to depress down all the way when installing the compensator.  If your plug is too long you will not be able to rotate the comp into place.   This is not the case for every buyer and if your spring plug is around 1.2" you should be fine.  We recommend it just to insure the fit but if your spring plug does not interfere with the install then you do not need to do anything.

How do I remove the compensator?

Will I need to use different screws or bushings with your grips?

You can purchase our grip screws by clicking HERE or as an add on item when you purchase a pair of our 1911 grips.  You should also be able to use your stock grips screws. 


How thick are the 1911 grips?  Can I install them on my double stack?

The 1911 grips are .22 inches thick.  Slightly slimmer than what is considered standard thickness but will not replace double stack grips.  


 Match Grade VS After Market?

Match grade usually means hand fit.  Basically that your barrel and slide have the tightest possible tolerances.  An after market part is a part made to the closest universal specs to fit the most models.  An after market part is not guaranteed to fit a match grade barrel 100% perfectly with zero fitting simply because the part was not custom made for your firearm.  We try to get as close to a universal fit as possible but unfortunately not all 1911's are exactly the same.
