Wilson Combat® Match-Grade Barrels are known for their unsurpassed quality and accuracy. Wilson Combat® match barrels are fully machined from aircraft grade stainless steel forgings and heat-treated to R/C 40 for maximum service life. Critical manufacturing tolerances are held to less than .0005" (one half thousandth of an inch!). To give you phenomenal accuracy, extreme care has been taken to assure that the chamber is glass smooth and perfectly concentric with the bore. In our barrel test fixture we routinely obtain test groups of 1/2" @ 25 yards; the accuracy is guaranteed to please YOU! Throughout the manufacturing process each barrel undergoes multiple quality-control checks, with a detailed final inspection prior to receiving the Wilson name. You can be sure that if your barrel bears the Wilson name, it's the best there is!

Now you can have superb accuracy (2" or less at 25 yds. with good ammo) without sending your pistol off to a master pistolsmith and waiting for months. Our "drop-in" barrel is exactly the same as our #33G match grade barrel, with the critical lock-up contact areas cut to a dimension that provides a good lock-up in most Colt and Springfield pistols. Due to variations in pistol dimensions, installation in some pistols may require very minor material removal which most people can easily do themselves.

Springfield Armory Inc. 1911A1 G I model 6/5/2018
I removed the Wilson Combat drop in barrel and bushing from my SA Mil-Spec model ,and tried it in my G I model at 7 yards with 230 hardball ammo . With SA G I Sights ,The Accuracy over the SA factory was unbelievable , punch one group hole at 11 Oclock from center man size target . I just wanted too know if buying another drop in barrel be worth the cost , even with the G I Sights . The Accuracy from Wilson Combat drop in barrel is worth every Penny . I found my Answer , Thank you Wilson Combat ....

Superb barrel 12/31/2015
I got this barrel for Christmas for my Kimber. After getting it to fit the bushing of which I used wilsons bullet proof bushing it has nearly a flush fit. I also ordered the 5 pack of barrel links to ensure everything went together ok. After very minor fitting it went together perfect. I also polished the feed ramps and chamber to glass and it cycles perfect. Feeds perfect. The Accuracy is beyond what I could have hoped for. Aim dead on it hits dead on. It will put rounds in the same hole when you take your time and use proper fundamentals. It took an old Kimber I bought as a toy when I came home from my first tour in Iraq in 2004 and made it a leathal tool Id happily take into a fight. THANK YOU Wilson!!!

very pleased 10/8/2014
The hood needed to be filed down a little on one side but once done, it fit perfectly and the bushing dropped right in. Very happy with Wilson products and I would recommend to anyone.

phenomenal product 9/2/2014
It is very rare that I come across an item that I consider exceptional to the point that it deserves extra time for me to take out of my day to review it. Even the worst items I ever bought did not get the extra attention. If there is any one part for your 1911 that you are going to buy, let it be a Wilson Combat barrel. After putting multiple barrels through my 1911, I have determined that in terms of fit, accuracy, and sheer overall quality, Wilson Combat barrels are unmatched. This gun improved my grouping by at least 2 inches at 40 yards.I would, without a doubt, trust their parts and workmanship with my life.

Kimber Saver! 6/12/2014
Got this Barrel for My Kimber Super Carry Custom. The barrel fit like a glove, no fitting just went right in. The bushing needed to be fit, but that was no big deal. This has saved my gun, 200 rounds so far without a single FTF. Where before it was at least once a mag. Thanks Wilson for excellent parts and service!

A must have..!! 11/18/2013
A must have if your serious about accuracy. Does require some fitting, but well worth it. Quality is excellant. Range results were awesome to say the least. Excellent product that worked well in my springfield loaded.

Colt 1911, .45 Series 70 1/12/2013
There is NO SUCH THING AS DROP IN! Please, do not kid yourself. The barrel improved accuracy, but every pistol and custom barrel is like a fingerprint--unique! I have many Wilson Parts in my pistol, but they all took a tweak and a twist to get them right.

I know who to recommend now 6/2/2010
Greetings. I just received a Wilson barrel from you, for a 45 acp AMT HARDBALLER. I am very impressed with the quality, and most of all, almost a perfect drop in fit. I only had to take a little off each side of the top hood, the bottom swing area needed a tiny bit, not much though. It fits so nice, it doesnt even need a finish chamber ream. My mouth almost dropped to the floor. It fits like a glove, I kid you not. Id just like to compliment your machine work, being I am a retired welder gladly from the UA Pipefitters Union, and a machinist for hobby. I do have a full machine shop for my toy room : Ive done a lot of air-smithing on match air pistols and rifles over the last 25 yrs, and some gun-smithing on firearms too. I tried a Baer barrel not too long ago, and after several hours of fitting it, I found that the factory chamber reaming was too deep by almost .100 , which was kind of frustrating if you can imagine. The Baer barrel took a lot more work for fitting too. Factory mistake, but it didnt impress me, for a match barrel. Anyways, just a token of appreciation for your quality machine work. I know who to recommend now : Nice job folks!! Thank you for your prompt shipping too. I should see how it shoots over the weekend. I like shooting Tens :
