I had two Bulldogs in the past, an older stainless 3" 'standard' configuration, and a 4" Target Bulldog. Both guns worked fine with the very limited use I gave them, though I couldn't shoot the 3" very well (probably me and not the gun.) The Target Bulldog had a surprisingly decent trigger and a very good balance, but was just a bit too light to keep steady for paper-punching...I could shoot far better with my 4" M. 15 S & W .38.
I eventually let both go, as they never quite satisfied, though I didn't have any complaints about their quality, the just weren't quite right for me and I became more interested in different guns.
I've been thinking off-and-on about picking up a new one with a bobbed hammer, strictly for a 'beater' CCW, but they aren't as inexpensive as they used to be! I can get a minty used SP101 for the same - or less - around here so I haven't been able to justify the purchase to myself.
I'd say if you find a new one at an acceptable price, and it seems tight, and you can live with the trigger, I'd give it a try. Just don't put anything approaching stout in it, and it will probably work fine. I guess one of the nice thngs about the .44 Special is that even the anemic factory "cowboy" loads are still pushing a big fat 200 - 246 gr. bullet out the end of the barrel, and I sure wouldn't want to be on the receiving end.
