If you go to the GT1911 forum here and do a search on the R1 you'll find most love theirs, with an occasional "needs trigger work" comment being about the worst comment you'll find.
Don't know about Remingtons CS after the fact but I'd suppose it to be ok.
Do a search there and read a bit, maybe, find the pros and cons. You already know Springfield is top notch in terms of customer support and they do have their custom shop as well... does remington have one for handgunsand if so, is it up to SAIs? Dunno, but I'd be asking those questions to them what have bought the R1.
It is a fins looking handgun. I wouldn't let the 80 series firing pin block stop a sale at all, but that's just me. YMMV
