Modern computer-machined barrels with tough tolerances allow enhancing the pistol’s potential accuracy and general performance. 1911 ramped barrels due to a built-in feed ramp have much easier caliber conversions for a frame. Match grade 1911 barrels and bushings are fully machined from premium-grade 416 stainless steel. Such barrels feature the chamber and bore of tighter tolerances.

Why do we need 1911 barrel?

1911 is popular due to its slim slide (about 0.9 in for many models). This gun is convenient to carry, either as a concealed carry or a packing gun for the out of doors. Match grade 1911 barrels are great for fitting due to the extra material in the areas where the barrel mates to the slide, allowing the gunsmith to remove just enough material to make a super tight lockup.

How to Install Barrel at COLT 1911

  • Some drop-in match grade barrels with a matching bushing may need sanding the metal from the barrel link pin (as they don’t have the barrel link pre-installed) and filing some steel from around the locking lugs on the barrel for proper pistol cycling.
  • If you have a Match Barrel, you will probably need a gunsmith to machine it and fit it to both a barrel bushing and a slide.
  • If you want to install a 1911 Auto match barrel by yourself, first measure the slide with a Digital Caliper (#539-832-218 or #606-500-136) to determine the hood length (usually about 1.314 in). Fit the barrel tightly (not too much) against the breech face.
  • There are two ways to hold the barrel squarely in the slide with the Barrel Alignment Block.
  • After measuring the breech face width, transfer them to the hood to file or mill to the actual necessary size.
  • Or paint the hood back with a black marker and gently tap the barrel against the breech face sides, then file the hood by hand.
  • After the correct fitting of hood length and width, lock up the barrel fully into the battery. The rear lug is oversized on the recess depth for slide fitting; it should be lowered until the barrel locks up completely to maximum lug depth. Center the barrel on the firing pin hole, having .045 in lug engagement to lock up.
  • How to measure the lock-up amount: put the barrel into the slide, without touching the breech face and seating into the slide lugs. A loose bushing can be useful to support the standard barrel muzzle without any binding.
  • While fitting a bull barrel, prevent barrel binding or springing as you push the barrel up into place.
  • There are two methods to fitting the bottom lugs on a 1911 Auto. The hand-cut approach means the bottom lugs are cut with the barrel installed in the frame. This way the lugs are in a direct relationship with the slide stop pin that they are going to lock up on.
  • After aligning the barrel square with the Alignment Block, insert a 1911 Auto Barrel Holder into the slide and remove the block. Fasten the barrel slide onto the frame and cut the barrel lower lugs with the Lug Cutter to allow the thumb safety to go into engagement to lock on the slide stop pin.
  • The slide back and frame should be flush, if not, you can remove odd metal later.
  • To provide better accuracy the flat on the lugs should be locked on the slide stop pin.
  • Mount the link and pin it into the barrel and handcycle. Check correct clearances for bushing or cone lockup at the pint: with the slide back over the hood and the barrel unlocked leave at least .005 in clearance between the slide upper lugs and the barrel top.
  • The barrel should be seated completely in its bed on the frame and the link bottom is not bottoming out in the frame. After being sure the pistol cycles without binding, proceed with chambering.
  • Check the chamber length and its diameter. Depending on the caliber, you may need to cut the chamber depth.
  • Fit a barrel with Wilson/Nowlin ramp or a Clark/Para ramp go by the barrel specs.
  • After cutting the barrel depth, fix the frame in the milling vise with the dust shroud pointing downward and the frame rails 45º from vertical. Cut a chamfer about .050 in wide at the intersection of those two previous cuts. Bevel the chamfer edges with a needle file, rounding them into a 1/16 in radius.
  • Fitting between bushing and slide should be tight, while a match bushing should be 0.001 in reamed over the barrel diameter. Chamfer the bushing top rear inside and lower front inside the barrel to ensure smooth locking and unlocking. During lockup, it should not spring back or bind when pushed up into the slide by hand.


How Long Will 1911 Barrels last?
The average service life of the 1911 barrel is about 5,000 rounds. After this shot quantity, the radial lugs can be rounded off or the lower lugs can break off.
What does a 1911-barrel bushing do?
The bushing barrel keeps the barrel duly aligned, ensuring the clearance for the barrel to tilt during the rifle recoils, making the next round loading easier. The bushing is fixed over the barrel muzzle, providing the barrel with centering and a solid platform for firing, when the slide goes back into the battery.
Are 1911 barrels interchangeable?
1911 barrels are not interchangeable, they often need some fitting, especially when changing a barrel from another brand. Some barrels, produced even by the same manufacturer, cannot drop in a gun from a similar or even the same model.
Can I put a longer barrel on my 1911?
The shooter is limited to the sight radius of the existing one in 1911. IMO won’t be significantly increased due to a longer barrel unless a red dot sight or a scope is used or the width between the sights is enlarged.


Choose 1911 barrels, made from Forged Stainless Steel, which are strong and long-lasting. Be attentive with the two most common kinds of ramped barrels, using a Para Ordnance ramp or a Wilson/Nowlin one, which are not interchangeable, as the frame bridge cut is different.
