I have both the Remmington .36 (Pietta) and my current favorite '51 Navy is a Uberti. Two different designs . . . two different "feels" to them. I agree with you on the finger space behind the trigger guard on the Remmie over the '51. My '51 has a square back guard - I like the looks of it but to be honest, I much preferred the rounded back trigger guards on the other '51 Navies that I've owned. While I much prefer the '51 Navy - it just feels better in my hand and seems to balance better . . . if I had to choose between the Remmie or the Colt it would be hard . . . both are excellent revolvers.
Congrats on your new toy Chaz . . . I think you are really going to like it! Let us know after you've had the chance to shoot it a few times.
