I own two of the H&R pistols that I purchased back in the early sixties, both have diguested many, many, bricks of ammo. Neither has ever given me a problem, nor do they show any evidence of excessive wear. The break top is still very tight, and very accurate, although it has been kicked around, and not always provided the best of care.
I strongly recommend the H&R if it can be purchased at a resonable price, I think you will find it a "fun gun", and reguardless of what anyone says, it should perform well for you for many years.
