I've got a Lone Wolf threaded G23 40>9mm and a non-threaded G27 40>9mm (both 3rd gen). Both have worked fine with only a mag change including suppressed and are probably as accurate as the Glock barrel; I can't say as I recall shooting them back to back for accuracy, just messing around with some run and gun style goofing off. I used KKM .45-10mm conversion barrels with, IIRC, 20# springs too; guess I got lucky as no issues with reliability (LW didn't offer them at the time I don't think).
