There's been plenty of Rough Rider threads in the past you can read through, but I guess I'll chime in here...
Pros:
-Cheap.
-Wood grips look good and feel good.
-C-O-L-T cocking is cool.
-Has never failed to fire a round, and it's been fed some dirty stuff. I save all my garbage 22LR ammo to put through revolvers.
-Accuracy isn't on the 617 laser beam level, but it's fine.
Cons:
-Some corners have clearly been cut to save money; barrel is LocTited in, metal finish looks like BBQ paint.
-Sights are kind of crappy and are fixed in place.
Neutral/No comment:
-The manual safety doesn't exactly inspire confidence, but I'm not carrying my HRR anywhere, so I don't worry about it. I just leave it set to off.
-Mine came with a 22 Mag cylinder, but I've never switched it in.
I'd say that overall, they're fun little things. Half of it IMO is just the tactile experience of loading and unloading a single action shell by shell, and these guns deliver that very cheaply.
The street price on the HRRs is always less than $200... for that much, I'd say just go ahead and buy it. They're not heirloom guns, but they're not turds either, and you won't be out much either way.
