They sell because they work good enough, not that they're that awesome lol. Don't get me wrong I have a 19 G4, and 17 G5 MOS but if I really want to shoot that's not the two I would grab. In the 80's and 90's you had the Sig P226, didn't really need anything else.I wouldn’t look for much change. I mean Why would they change something that has sold the world over and works? Until Gaston is not involved I would be surprised if something new came out. I could care less about forward slide serrations but I never thought I’d see the day they would be standard in several models. That was a surprise to me.
I’m just glad we have the options if makes and models of good guns these days than we did in the mid 1980’s
