Welcome to cas city, you cant go wrong with a .45. Easy cartridge to reload. Marlins are good guns with a few exceptions. Ubertis and Rugers make fine revolvers. The only Marlin parts I’ve ever broken were a couple one piece aftermarket firing pins and a lifter, before I did the jbweld repair, don’t remember having an extractor or ejector break. Never broken anything on my .45 Rugers. Ubertis are another story and some are fine and others need work to become cas guns. As occasional plinkers they are usually ok.
