Was thrilled when I got a MKIII 22/45 LITE. Of course the trigger needed work so Volquartsen parts here I come. Great improvement.
Then I decided to try bullseye shooting and LITE just wasn't me so I hunted for a LLV till I found a price I could accept. WOW, what a difference! (The factory upper now needs a new home as its a dust collector today.)
Then it was a need to change grips. Well 1911 grips fit, sorta. Just took some modest Dremel work for the buttons.

Wish I could find something I might like than the set I now have. Looking for something like the Volquartsen grips which fit a MKIII 22/45 frame.
I'm still resisting getting a MKIV...
