I have an old 3" Bulldog model that I bought in 1977.
Still tight, still accurate with loads it likes, and it has the lightest smoothest factory trigger I've ever felt.
I once heard a gunshop owner running down the triggers of Charter prvolvers. Rather than argue, I got my old Bulldog out of the glove box and let him get a feel. I wish I had a photo of hte change in his expression as he squeezed that trigger.
Just remember, these guns were made to be carried more than shot.
