Like Gibby, I never had any function/reliability issues with my Rowland on the Mil Sec Springfield. Uses the .45 ACP magazines, and no problems with them and this round. My only issue, as I've said, was the noise level caused by the comp, but Clark told me that taking the comp off will cause the recoil to beat the pistol to death in short order. The .460 was a blast - pun intended - to shoot, and accurate. After having issues with 10mm in a Glock, I felt much more comfortable shooting the Rowland. I certainly would not discourage anyone from trying it. I gave Clark a list of "pre-owned" 1911's I was considering for the conversion, and they recommended the Springfield over some much more expensive pistols.
