the 4 inch barrel make it tough as most officers model 1911s have a 3.5 inch barrel look at Kimber and springfield (Ria is a 3.5)

Most every (4.25" barrel) Commander sized pistol I've seen all carry a barrel bushing; but not all as a few select manf do use a bull barrel. Now compact or (4.0" or less) Officer sized 1911 platforms mostly use what is called a "bull barrel" which by design locate the barrel in the slide like a funnel fitting inside of a funnel, this system works very well too. I have a Commander (4.25" barrel) with a bull barrel and no barrel bushing. Rock Island Armory has the RIA_51417 Model : ---- keelyarms.com/product_p/ria_51417.htm ----- (It is in stock here): https://anthonysfirearmwarehouse.com/store/ria-1911-45acp-midsize-gi-4-25-8rd-133331/
