Well, yours is better than the new M66 a co worker showed me. It spit lead so bad he couldn't get a box of ammo through it. He sent it in along with a check for a master action job. It came back with a reasonable trigger but it would not ignite all loads so we pulled the stocks and apparently the strain screw that was used in the original gun was not long enough to put the pressure needed on the ribbed spring S&W had installed. Their solution was to send him a new strain screw. The problem, they sent him the exact same screw he already had in the gun.

Our solution was to go back to the flat mainspring and live with the heavier pull weight.
All this fiddling around took over seven months.

Nobody's perfect but where does the sloppiness end and why does S&W not fix their final inspection department?
