I don't recommend DA either, SA is the way to roll...they have a p*ss poor timing system. The '92's are an improvement, but in a cobbled together kind of way. Whomever was responsible at Colt for this debacle...shame!
Be glad to help if I can. I run about 4.2 - 4.5 grains of Unique under an Old West HB 195 grain mold...PL of course. 4.2 is what you expect, 4.5 is not a plinking round...you know you've shot something.
Pity yours doesn't have the relief machining for upgrading, I've 2 '92's to upgrade with ( 38 LC...pick them up for 200 $...parts pistols).
Stay safe
