I just picked up a barely used G48, finally putting rounds downrange tomorrow. It's really light and slim plus the grip feels great- it's going to be the perfect non RDS summer carry gun for me.
My only concern is replacing the sights- I'm finding very contradictory info on if 43 sights will work so I just put on a set of Trijicons and will find out soon enough. I'm not crazy about the silver finish, but it's growing on me. I accidentally scraped the holy hell out of it installing the sights and the scratches pretty much wiped off, so it seems pretty durable. And everyone needs a pimp gun at some point, right?
