The Advantages of Investing in a Quality 1911 Barrel Upgrade

Like other upgrades, investing in a top quality 1911 barrel has its advantages and benefits. However, you’ll need to consider some of the gunsmith benefits of a good quality product. Here are some things to consider before making your concluding decision:

Better Accuracy

It is at no surprise that owners want their pistols to be accurate. If you choose to invest in a quality gunsmith 1911 barrels, then you’ll get to enjoy the great advantage of having a more accurate gun.

Long Lasting

Some factory 1911 barrels may not last as long as you wish it to be. That’s why it is important to invest in a better quality choice. You should find one that is made from durable enough material that would make it easy to clean and less disposed of to long term damage.

Compatibility with Bullets

In the past, some 1911 barrels have worked well with resonating points. Over time, some don’t feed hollow points as smoothly as they do long ago. A prodigious product should be one that will work smoothly with most bullets, including lead bullets.

What Makes a Great 1911 Barrel?

This is a common question that most best barrels owners will ask a lot. What are some of the aspects that make these barrels great compared to some of the five options that are on the market? Here are some of the things that may factor into what would make one stand out:

A Perfect Fit

Obviously, the best 1911 barrel has to be one that fits your gun nicely. It doesn’t matter if it’s convenient to install or if it needs to be installed professionally by a gunsmith. If it can fit your gun perfectly, then chances are that it will stand the test of time and usage when compared to cheaper models.


Sometimes, finding the best 1911 barrel may be a huge products budget problem for Sig Sauer guns. However, just because you’re on a tight budget, doesn’t mean you have to find a cheap one that will factory up only lasting a short period of time. So, find the best guns that you can afford in terms of quality. The last thing you want is to fork out more money each time your device fails.


Sometimes, you’ll have to consider the length as one of the best leading factors in your decision. Typically, the shorter the length, the faster you can get a shot off. This is an important thing to remember if you’re planning to use your 1911 for home defense purposes. A shorter barrel may also be ideal if you’re using your gun for competition purposes. Other than that, the length of a 1911 will regulate the feet per second of every pre fit accuracy round you shoot off.

Frequently Asked Questions (FAQs)

How do I put up a 1911 barrel on my gun?

Fitting a 1911 barrel can be a challenge for some people. But with clear instructions, you can make it relaxed just by following along. Here are the straightforward steps you’ll need to take to fit a barrel on your 1911:

Step 1: Slip the barrel into the stuff and check the hooded sides. Each sides should be clear the lower locking lugs are true up and down.

Step 2: Next, check the 1911 barrel length. You should try assemble the barrel to see if it will fit up into the slide locking recesses. If it won’t, then proceed to remove a small amount of length.

Step 3: Now, install the barrel with the link, link pin, and bushing, then trial assemble slide, barrel, and frame. If it properly fits like a charm, then it will hit hard on the back of the hood. It will also hit really hard on the lower locking lugs and evenly on each side of the top locking grooves. It should never touch any place else, except for the bushing. At this point, you should be able to press the gun in the locked position with only your thumb pressure. It will have minimal, if any, movement in any direction.

Step 4: The barrel is locked at 0 at the lower locking lug. Further movement will wedge everything else into position, except the link when the gun is locked. You’ll notice a flat in between the slide stop pin lower locking area and the front radius on its lower locking lugs. The measurement for appropriate operation should be .030. It can be increased to .060 to help the slide be flusher with the rear of the frame. If you really want this, remove the metal from the rear of the locking lug with a 3/16 inches rat tail file or a milling machine. This will allow the stop pin to lock the barrel somewhat further to the rear. If the .030 inches is increased, the link pin hole will most likely open up to prevent binding.

Step 5: Once you’re satisfied with the fit, slide, and frame assembly, then install the link and the link pin and check for any link pin interference. If you have the slide upside down in your hand and the barrel installed, you can still be able to move the link slightly more while the slide stop is pressed to its rear. If not, you’ll need to open the slide top pin hole in the link slightly on its bottom side.

Step 6: Finally, you’ll want to end the chamber with a .45 ACP finish reamer to 0.898 inches or up to 0.91 inches measured from the end of the hood. This may not be needed if a small amount of hood material was removed during the original fitting. You’ll also need to finish with a 9mm reamer to 0.754 inches to 0.776 inches measured from the end of the hood. Then, use a .38 Super finish reamer to .890 inches to .900 inches.

How Long Will 1911 Barrels last?

The average life span of this pistol barrel is about 5,000 rounds. Afterwards, the radial lugs can be rounded off or the lower lugs can break off.

What does a 1911-barrel bushing do?

The bushing barrel ensure the barrel are aligned, allowing the clearance of the barrel so it can tilt during rifle recoils which allow follow-up rounds to be smooth sailing. Most often, the bushing is located over the barrel muzzle, so it offers stability to the barrel with study platform when firing shots.
