After comparing my G19c to a friends G23, I noticed his G23 has a additional circular mark or punch out on the frame of his. The circular mark my G19c has is located just behind the disassembly latch (bottom right corner of the pic below). His G23 has a additional circular mark above the one on my G19c.
Any ideas what these circle thingys are, and why the G23 has two??
