Trigger pull poundage on revolvers and semi's are a deal killer.

In IDPA, we see a lot of kids and newly divorced women learn to shoot, change mags, clear Fail To Fire, etc. Trigger pull is their main obstacle to over come

Children(young adults) and small women have a hard time with very heavy trigger pull.

One thing for sure, 17-20 round 9mm gives them a lot of confidence, especially the women fearful of their agressive X.
