I have one [AWA] that I've been very pleased with. .38 special. I've used it in a couple of matches with no problems out-of-the-box. I haven't had anything done to it, but I have been planning to strip it down for a cleaning and look for any burrs, etc. The manual recommends RNFP, but I have occasionally used wad cutters and RN when it was all I had, without problems. Being a tube magazine, I'd recommend couldn't hurt to stick to some kind of flat nose.
I'm actually considering getting one in .45LC too (or maybe a Henry), so yes, I'd buy another.
