May I suggest that you replace the hammer return spring? I regret that I didn't keep better notes, so I can't tell you exactly which Wolffe spring and which poundage, but I replaced the hammer return spring in both my 75 Compact and my 83. They are now both a dream to shoot. DA about 4 1/2 lbs and SA about 2 1/2 to 3 lbs in both of them. I haven't had any problems with ammo FTF. I do have to remember that the SA pull is pretty light. Every once in a while, I'll do an unintentional "double tap".
The 83 has the sweetest trigger I've ever pulled. It's absolutely terrific - both DA and SA. The 75 Compact SA is a little crisper than the 83, but not quite as smooth. I recommend it. You can do it yourself in about 10 minutes (less if you know what you're doing).
