Slims do funny things to the "feel" of the gun but they also change the basic geometry of the hand.
First, if you do try a slim set get the new slim bushings and screws or you will ruin the slims by trying to fit them on the existing bushings. Trust me on this one! If you don’t break out the molded in shoulders you will have screw interference with the mag. (Or both)
I have average to large hands and what I found going to the slims, for better conceal carry, moved my trigger finger forward. (Less gun to hold) This required a “long trigger” to be installed for proper finger pad to trigger interface. I loved the slims but just couldn’t adjust to the extra distance my finger needed to travel back just to make contact.
I like my slims, but had no idea going in that it was a bigger change than just the grips.
