The gen.-4 I tried was a 22, but it did NOT feel good in my hands. The new finish felt like a combination of a wire brush--points OUT!--and VERY-course sandpaper. I have a gen.-1 23 and love it, but I wanted something I could mount a lite on, and Glock's shorty lites seemed just right. Bought the 23 locally (Scottsdale Gun Club), and--surprise!--it came with an adjustable rear sight. That made it about $40 'less expensive', at the same $500 retail, as Lone Wolf's. SGC doesn't sell the Glock lights, so I ordered one online. Shot 110 rounds of 4 different reloads thru it today with NO malfunctions of any kind. With all the malfunctions 'The American Rifleman' found in the recent test of a bunch of 380ACP subcompacts, I'm very pleased with this result.
