S&W triggers

A whole SLEW of gunbloggers have 'drunk the Kool Aid' and purchased the S&W M&P pistol, usually in 9mm.  They have almost always bought the Apex aftermarket trigger to go along with the new gatt. It is cheap, easy to install, and the satisfaction with the improvement is so extraordinary I half expect S&W to buy out Apex and make the better trigger standard.

But there is zero chance I will buy an M&P, so there is no way I can get in on the fun...  Or IS there...

Well, lookee... They make a drop in trigger improvement for J-Frames.  I wonder what that will do for me.  Hmmm.

Here is a question.  People unfamiliar with my snubbie will pull the trigger all the way back, slowly, and the hammer won't trip.  so:  Squeeeeeeeeeeze, nothing.  I know that they just need to pull a hair more that they haven't pulled it ALL the way back.  It did this to me until I knew to pull with authority.  Is there something there I should be worried about correcting?  If I had more experience with LOTS of revolvers I might know this already.  Maybe if I get the sideplate off I'll see it.  But I bet there is even a NAME for this phenomena and some more knowledgeable gun enthusiast will tell me.
