Kimber no longer makes their 1911 or conversion unit in 17M2. Supposedly they do not run well. We have had good function with CCI/Hornady ammo. Eley/Remington will not run any of the guns/conversions that I know of. My personnal 1911 in Mach2 has digested several thousand rounds(at least) with so little trouble it's not worth the mention.
If you know of any guns or conversions out there others would like to know where/who/phone#/ etc...................
