So to be clear, I've made about 20 measurements on the grip, not a single location is large enough to accept the lower. In addition I have tried stretching the plastic and it can't be stretched to fit without serious concerns of breaking the part. I'm not *****ing because the part is a little out of spec, the damn thing can not fit!
Gotta be honest, disappointing experience with most of you calguns members. Seems like your brand loyalty is influencing your responses to someone who's having a legitimate problem.
The entire point of this post was to remind people, especially new buyers, to check what they bring home. Manufacturers make mistakes, parts get left out of assemblies, it happens. Either way I'm done with this thread.
