500 I completely agree with you. We have only a couple extremely competent gunsmith here in our country. However they can do anything I have seen in the US, and many times I have seen them do it better. Unfortunately we probably have 100 lousy ones...
Our problem is they have not as much experience with doubles and less with big bore doubles.They are shotgun and bolt action rifle masters.

So the problem is knowing what to ask them to do. If you say the triggers need longer travel and 3lbs or 4lbs, we can do exactly it. The problem is knowing what is right.

If 5-6 lbs is right, then we will leave the triggers alone...exactly as you suggest...
