after waiting for 3 weeks I finally got my glock 21c. Apparently, all the gen 4s were recalled so not wanting to wait I went with the gen 3. The guy at high country said the gen 3's were outperforming the gen 4s all day. Theyll get it fixed soon. I was looking forward to the changable grips. I will be happy when I get some new sights on it. Anyone use the pyramid sights?
