Got my 75 SA back from CZUSA the other day, 3 week turnaround time. New trigger is the steel unit, after the poly broke, I was hesitant to try the aluminum. My pistol also received the standard 'SA trigger job' as has been discussed in previous posts, overall pull is reduced slightly but the big improvement is eliminating the multi stage feel apparent in the stock mechanicals. The operation of the firing pin block seems to occur much closer to sear release, hammer camming action is greatly reduced so you don't have to fight the mainspring as much. You pull against the trigger return spring for about 1/4 inch, the trigger firms up as you come up against the sear and it breaks cleanly and very predictably. Anybody who is considering replacement of the stock trigger to gain a pre-travel adjustment, it's probably not worth the time or expense, as disconnector geometry still requires a fair amount of release travel to reset the trigger. I experimented with mine and found myself back to Mike's setting of reset position plus 1/4 turn.
