I have a glock 30s, trust me it's not worth all that time or effort lol. Glockmeister sells slides and receivers and people have been buying a Glock 36 and just ordering the 30 SF lower. I'm fairly certain Glock has a Gen 4 30s in the works, one of the shot show interviews alluded to it. I'd hold out for now.
