Well I'm going against the grain. I own a 1954 model Sportsman, traded for it used ,had to do a little a little work on it. The revolver was in time double action but had some issues with the cylinder binding single action, that was solved by replacing a bent pin that lets the bolt drop.Then it had a light strike problem, the previous owner shot a lot of shorts through it and it needed a good cleaning with 0000 to clean the chambers and I also chamfered the chamber mouths. Also had to lock tite the rear sight ajustment screws, they will shoot loose if you don't.
That being said and done the little revolver is as reliable as the day is long, it locks up tight, never shaves any lead and is way more accurate than I am able to shoot . It is light ,handy, accurate and not to bad a looking revolver. I am looking forward to squirrel season, and it will have a place on my hip.
The other H&R was one of the convertible models 22-22mag, kind of a western look 600 series, and I wish I would have kept that one. It was an onery looking thing with the plow handle grip, and it was double action to boot. Bought it nearly new and never had any issues with that one.
See if the shop will let you test drive the Sporsts man, you may find out it is shooter.
The price can be dickered for, depending how the pistol shoots.
drop WOAD YURT a PM, he is a H&R nut might be able to give you more info.
