I've had two, both Springfield's. Both required warranty work which was painless and completely satisfying. Both ran flawlessly, the warranty work was not for function. I got rid of them to fund some other project that I don't even remember. Currently I have a Colt Government in .38 SA which also runs great. I've fed it factory, underpowered reloads and over powered reloads. It handles them all. With the 9mm I used Springfield's ramped magazines. In the Colt I use Wilson, Mec-gar, Colt and some other well thought of brand whose name escapes me.. All work.
