I had a couple but sold 'em... Considering divesting 10mm altogether. Nothing wrong with 10mm at all, I like it, I just don't use it enough. Want an FNX-T now.
I'd go with factory stuff but you do you.
I know I'll get questions about that.... The factory stuff just works better when talking about Glocks IMO/E.
Not a real fan of the LW stuff, but I was one of the ones prodding 'em back in the 90's to make a 10mm longslide. I can't bitch, they did deliver... Just was a heavy motherfucker and I don't see how they can be reliable. I had 'em make one in a practical/tactical style, 5.35" I think, and that one was better, top cut, but still heavy.
