It was either this one or my G31, but I know that I use the 23 more often. I'm experimenting with these, Meprolights and stock Glock Trijicons to determine which works best. The straight eight design is something new for me. Going to the range later to sight in, will use the G23 for GSSF later this month. Tools used: MGW Glock rear sight pusher. Ed Brown Front sight tool, with adaptable screw driver. Pliers, used for the original Glock front sight that was staked in. Hex key to adjust set screw. What do you guys think?
