I stupidly sold my Ruger Old Army a while back and regret it now but anyway, just seen a very attractive ROA with a 5.5" barrel advertised online but the seller is asking a fair bit more for it due to it's apparently superb condition and the fact that it has the shorter barrel. My question is, are the shorter barrelled ROA's as rare as the seller says ? Personally I've never handled one but love the look...
