Any compact 1911 is more prone to problems than a full size 1911.
I have done more transfers with RIA than ATI. I haven't had an ATI come through in a couple of years. And when I did, there were parts replaced on the ATIs within a few months.
ATI may have gotten better, but I have no direct knowledge.
