I hope the "improvements" didn't lead to even more fiddly little parts.
I realize they have to tap dance around Glock's ignition design, so I try to be understanding. But the 2.0 version's fancy new sculpturing and textures don't mean squat to the functioning of the pistol. And the current version draws enough blood.
Given a choice I'll still take a plain, unsculpted, ugly Gen2/Gen3 Glock that goes bang every time, has a decent trigger pull, and contains an amazingly low list of parts to fail.
