An often asked question is if our OPF-G (Optics Platform FCD, Glock) plates, designed and made for 9mm 1" slides work on wider slides, such as G20, G21, G22, G23, G40 and G41. The short answer is OPF-G, RMR, OPF-G, RMRcc, OPF-G, DPP, OPF-G, EFLX, and OPF-G, ACRO all work with the wider G20 and G21 (1.12") and G22, G23 (1.08") wide slides.
All but OPF-G, RMR will leave a slight gap on both sides of the plate. This gap is cosmetic only, it's either we have a "step" between the plate and slide, or a step between the sight and plate if we made the plates wider. A wider plate to accommodate the wider slide will not do a thing better.
OPF-G, RMR is wider, as RMR and SRO are wider than RMRcc, DPP, EFLX and ACRO. OPF-G, RMR does not leave a gap between the plate and slide, but the front two corners contour was made for 1" 9mm slides, the contour doesn't match the corners of wider slides.
We have no plans to make wider plates for these models with slightly wider slides, as it'd only be cosmetic. Wider plates for specific models can confuse customers, and will complicate logistics for us and our dealers.
Below pictures illustrate how OPF-G, RMR,, OPF-G, DPP, OPF-G, EFLX, and OPF-G, ACRO look on a G20 (1.12" wide) slide.
