I cant tell the difference between the two. Ive got the dropin kit in my poly TG 10/17HM2 and the volq accurizing kit in my 22/45 lite. Both are awesome triggers, Im sure youll be happy with them.
Just installed the Kidd trigger job kit. Very very nice, worth every penny. Also got their bolt stop pin, vastly superior to any of the other plastic ones I have tried. Very happy with Kidd.
