Apex is ok. Wilson combat is better.
I have a well broken in 442 with an action enhancement done by S&W. Took a chance and subsequently for $25 dropped in the Apex kit. No real noticeable improvement. Trigger pull is 9.65 as measured by my Lyman trigger pull gauge. ( I think apex is stretching it a bit when they say you'll get down to 9 lbs..). Picked up a 340pd tuned by Tom Kilhoffer at TK custom. Decided this time to try the Wilson combat kit from Midway. I used the 8 lb hammer and 13 lb rebound spring and even went so far as to put in a new extended firing pin from Apex. Gun has 115 live rounds fired. Only about 10 were 357. Also have dry fired over 1000x. The trigger pull on the 340pd is 9.13 lbs.. I'd recommend the Wilson combat over the Apex.
