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.
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:
