I insist on a good trigger pull. I don't shoot well without one. There must be no take up, no creep and only the slightest overtravel.
Be careful who you send it to for the work. Make sure they understand exactly what you are looking for. I had the triggers (mechanical) done on my Superposed. It was a waste of money, because they came back a little worse than they originally were.
I gave my Perazzi trigger to G. He did a superb job and I loved using that trigger. Unfortunately, it only lasted for 3000 before it became so light I started short shooting and flinching. I then gave it to W. I got back exactly what I asked for, but after 200 rounds the trigger had dropped by 1/2 pound.
I sent the trigger to Kerry Allor. I was having him do barrel work at the time. A friend who used to live in the midwest and knew Kerry told me that although he was known for his barrel work, he was also the best Perazzi trigger man on the planet. What I got back was stunningly good, just what I asked for, and more importantly, is still just as good. Kerry told me that if a trigger job didn't last at least 15,000 shots, it wasn't done correctly. Well, at lease on the bottom barrel, I'm past that and it is still the same as when he sent it back to me.
Kerry also works on many other brands of guns and triggers. So I'd give him a call and see what he has to say.
