I was at Glock's Shot Show booth yesterday. Believe me when I say that they still don't have an R&D department. Nothing new ever. The Gen 4 was the most anti-climactic "new" product at the show. It's nothing but an SF model that you can snap cheesy panels onto if you want it bulkier than the standard SF. What a load of crap.
I'd be a better listener if you stopped talking about stupid crap that doesn't matter.
