Stay away from H&R
I have 1 old H&R 38 I found years ago for $80. it was a little worn finish wise and had the hammer spur bobded but it was nearly mint mechanical condition, I say was. First the trigger spring broke then the hand spring then the sear then it got out of time. All before I shot 50 rounds out of it! It been sitting in a drawer now for about 3yrs ever since I quit putting money in, gun smiths. If it was not my first revolver I would chuck it in the trash heap.
Now that said I am a firm believer in th superiority of top-break revolvers, especially "British" top break revolvers, and most especially the Webley.
I carry a Webley Mk6 every day on the farm and it is great. It weighs 38 ounces empty and is 11..... something in length. It been rechambered for 45acp and is my one of my most acurate revolvers, also though the sights are fixed they are "combat" style and pretty visable.
Of course you have to keep the loads on the low side but even at 700fps with a 230-250gr slug it has plenty of power, and parts are still available from several dealers. I would suggest you put a parts kit together just in case they ever run out.
Also the 45acp models can still be found for under $400. Even less if they have bad finishes or mixup parts.
The main parts that tend to break are the mainspring and the barrel catch spring, but "V" springs(both broke on mine) and can easily be replaced with new production ones if your inclined.
The trigger pull on most is heavy but smooth, and if this concerns you be ready to spend a little more
and look for a Webley-Green (WG) model, they have a trigger that rivals a Colt Python.
