Can anybody confirm if this is normal internal wear for a Gen 4 Glock 23? It would appear that the RSA is scraping the receiver while it is being compressed and/or disassembly. This is a non issue on previous generations and I believe it may be attributed to a larger spring. Also, is the frame battering normal? Would anybody expect this to continue? I am at approximately 1000 rounds...no hot loads or reloads.
