To all the folks saying they might give a TT connector a try based on my subjective evaluation of one part in one gun: give me the weekend and I'll put one in an otherwise stock gun. I'll measure the weight change and also see if it gives the same qualitative change in trigger feel.
I'd hate folks to go out and spend money on the connector (and shipping, which is probably half as much as the connector itself) just to find out that mine was the fluke.
