Does delta and trijicon share same mount..that THICK mount that sti came withI appreciate the durability of the RMR, but the size of the window and removal of the sight for a battery change was a deal breaker for me. I've got just under 5k rounds combined through both of these guns with no real issues in regards to the DPPs, other than mounting screws coming loose, but it appears I've figured that out as well.
The size of the window and top loading battery compartment were the deciding factors for me.
