I found a place on Amazon with a holster for the R51. From the Amazon photo it looked exactly like the R51 holster on the Remington website. I ordered it and received it today. It DOES look exactly like Remington's holster. It is very well made, the fit is superb, and the retaining strap goes over the back of the slide NOT over the grip safety. It's made by J&J Leather Sales out of Ocala, FL specifically for the R51. The only differences are that instead of a Remington embossing on the front it is embossed with J&J and it's about $20 cheaper ($44.95 plus shipping).
