Good choice! I have a SF, bought new when they first came out, but I'd never sell it. Carried daily in a Mitch Rosen Pocket Softie, shot a few times a year. It's been 100% reliable however the black coating has worn away in many areas. Gives it character. I believe I paid $1795 back in 2009 from a gentleman FFL in Florida, and at the time it sure seemed like a lot for a little pocket gun. Hell it WAS a lot but who else back then (or today) sells a small 9mm pocket gun that's reliable, accurate and has such a sweet trigger? I picked up half a dozen magazines from the factory and it's been my partner ever since. It's so small I have to touch my pocket to check if I have it with me.
Good luck finding a NIB R9SF. There was a time back in 2009 that I received a couple email offers for double what I paid.
Recently I purchased an R9S from the man with his name on the side of the gun - and that one sits in the safe until I or the SF bite the dust. Will Remington ever release its version of the R9?
