u/Dorado76

Locking block on the left is OEM and locking block to the right is from GlockStore. I Ordered a complete lower parts kit for a build using the slimline Grit Grips 43X. The GS block is was out of spec and not a true 43X fit. Didn’t even fit in my original Glock frame.. Disappointed that I’m stuck with a paper weight but we live and we learn. Emailed customer service on Monday and still no reply.
