Oddly enough the Remington design won out to this current day and the Colt style was dropped.
Well not really. The Military requested a top strap design. The '71/'72 Open Top was to be Colts entry. Of course the Model P was then offered.
So there may be some and some, Colt better for BP and Rem for cartridges? Yea verily where does that leave us with Cartridge conversions?
Again, not really. Turns out the open-top platform is quite capable of handling 45acp+p loads . . . better than many modern "top strap" revolvers . . . ( the Colt Mod P for instance!)
Remington's do very well with conversions but I haven't had a chance to test any "heavy" loads yet ( it's in the very near future . . . like maybe next week).
Now with all due respect the Colt style looks like something out of the depths of the ocean for not aesthetically pleasing (sometimes known as ugly)
That said the biggest baddest one of all (Colt Walker) is the one that appeals to me. Sometimes ugly just has beauty of its own.
And sometimes beauty can be in the eye of the beholder.
Yes, the eye of the beholder. I for one think they are by far the finest looking revolvers ever produced.
This is all I can show of this one since it's. . well . . unmentionable . . .
