Questions & Answers
Will it fit in Kimber 1911 full-size 45 ACP ? Expert Answer

The Ed Brown Products Suppressor-Ready 1911 Pistol Barrel will likely work with your Kimber 1911. However, you would need to know the specific model in order to determine if the Ed Brown Products Suppressor-Ready 1911 Pistol Barrels in 45 ACP will work. If you have a 5" barrel model Kimber 1911, one of the Ed Brown Products Suppressor-Ready 1911 Pistol Barrels 5" 45 ACP models should work but I recommend contacting the manufacturer to confirm compatibility.

need threaded barrel for sr1911 commander Expert Answer

Your 1911 commander can use a threaded barrel (4.25") for 9mm or 45 acp depending on what your SR1911 in chambered in. MPN:9243-9MM-SR (9mm) or MPN:9243-45-SR (45 acp). You can also use the Nighthawk Custom Match Grade 1911 Threaded Barrel found using the following link:

Worked great! by Satisfied, March 13, 2024
Wanted a threaded barrel for my Colt. This one worked great with very little fitting and improved the accuracy noticeably. No, the thread protector was not the one in the picture, but it was way cooler. The correct one can be seen on EB website.

High quality by GUY333, Verified Owner, February 19, 2026

Product Info for Ed Brown Products Suppressor-Ready 1911 Pistol Barrel

Identical to the Ed Brown drop-in barrel, but longer length and threaded for use with suppressors. Thread size is 0.578 x 28 tpi RH on the 45 ACP barrels and 1/2 x 28 tpi RH on the 9mm barrels. Includes link, link pin, bushing and thread protector.image

Please note we do not deal in suppressors; we make the barrel you will need to make the 1911 suppressor ready. You must procure the suppressor from another vendor, and be aware that states have different laws regarding suppressors.

A suppressor equipped with a Nielsen device is REQUIRED for reliability in a 1911 device. This is also referred to as a booster, kicker, or Linear Inertial Decoupler. We use and recommend the Black Reign suppressor by Elite Iron.
