I just texted Scott from Zev and he said they are selling stripped slides.
For the record: I still love my Zev modded glocks.
Thanks for the reply. I know you're from PA but I'm not sure what part, so this might be a long shot, but have you dealt with Syndicate Arms? They are out of Wexford and are the only distributor even remotely close to me.
Worst case, I call and talk to someone at zev direct and get on the same page and send out what I have to. Everything they do looks awesome.
