Mine got the Walrep hammer shaving in Jan 2003, along with a firing pin spring replacement. No issues since.
CCI Mini-Mags are great, but yes, pricey. So, I use quite a bit of the Bulk Remington goldens from Wally World, and I just deal with the duds.
CCI Standards, CCI Greentag, Wolf Target all function fine. The Greentag is the most accurate.
