I congratulate the OP on his new purchase. I do like the faux case hardening on the aluminum cylinder frame. It's a nice looking revolver.
It's something that other companies should use on aluminum receivers, if it's durable and resists cleaning solvents well.
Perhaps Heritage is introducing new finishes and barrel lengths to compete with the fairly plain finish Cerakote finish and 4.62" barrel length on Ruger Wranglers. Wranglers are still selling like hotcakes in the low cost .22 revolver market though, so variety seems not only a smart strategy, but an essential one. (Gotta love capitalism) Full marks to Heritage for innovative marketing.
I understand that both the Rough Rider and the Wrangler are beer budget plinkers, and that both of them make a lot of compromises to achieve a low, low price point. (aluminum cylinder frame and zinc alloy grip frame) But, I still find the Rough Rider less appealing. The square trigger guard shape, external manual safety, cemented-in barrel, and plastic parts just do not appeal to me. But, that's just my opinion.
The Rough Rider does cost less because of these compromises, and many people won't mind them because of this.
I also prefer the all coil and music wire springs and transfer-bar action on the Wrangler, which duplicates the Single Six internally.
On the other hand, Heritage has a great warranty policy and will mail you replacement parts quickly by mail, and usually free of charge.
Flat springs like the trigger / bolt spring do break on all SA revolvers that use them eventually, unfortunately.
But all of the Colt SAA clones and BP revolvers use them, and these remain very popular revolvers just the same.
Like I said, these are merely my opinions and I am sure that others will disagree.
And I am sure that the OP will have a lot of fun shooting his Rough Rider and that it will give him good service for the money.
