I love my GP100. I think it's probably one of, if not the most rugged, dependable, and well-engineered service revolvers ever.
I do prefer the full lug, though. The GP is a stout little beast, and it looks off-balance to my eye with a half-shroud.
They used to make GP100s with half-shroud barrels, but they were dropped more than a decade ago. I've never seen one in person.
I, personally, wish they'd bring back what they used to call "Target Grey".
Not pretty, but functional. The GP really isn't a fancy barbeque gun. It's a working revolver. Ruger has tried to make nice and purdy versions before, like the Royal Phoenix.
I'm fond of the Wiley Clapp edition. One of these could easily be an EDC for me.
Then there's the Ruger Redhawk S, which is I think a blank firing pistol or an airsoft gun. Either way, I kind of wish they'd make a GP100 like this.
