Some custom shops turn out decent trigger work, but some don't seem to do much more than you can do yourself.....for a whole lot less money. I once sent a colt saa to a very famous guy that worked on them. Not being one to say unsavory things about a person that is deceased, I won't mention his name. It needed some timing work and a new front sight installed. He also offered a "package that included sight in". To make a story short, it was poorly done and still didn't shoot to point of aim when I got it back. He said it needed a new front sight and he didn't do that sort of work. Frustrated at spending a lot of money for next to nothing, I indexed the barrel and installed a new front sight myself. Custom shops can sometimes be better than others..but always charge more than you can do it for yourself. I still vote for spring replacement and letting the action work in a little before resorting to spending a lot of money on it.
