Choosing Between Them
My top recommendation is the Monstrum S&W M&P Plate, which I suggest for S&W M&P pistol owners who need a rock-solid RMR interface. The lineup also covers Sig Sauer enthusiasts with the Sig-specific variant, Glock builders with the standard and highlighted base plates, Taurus owners with the PT series mount, and Ruger rimfire fans with the ADE adapter.
The critical caveat here is that none of these mounting plates fit the Browning Buck Mark properly, despite how you might search for them. If you own a Buck Mark, you should keep searching for a dedicated rimfire adapter rather than trying to force any of these options to work.
