If finances dictate, try to straighten or get some of the RIMZ. However, you're shooting a .45 cal so money is probably not the biggest concern. Not sure why you would want to waste your time straightening them. They are not that expensive. Contact Ranch Products directly. You have to send in a money order and it's a little bit of a hassle, but in bulk, that's the cheapest way to get moonclips and for what it's worth, they work very well in my 625PC. I also got some for my 940 from them and the work well also.
