A magazine article had grips dimentioned out the LaRue being one of the largest.I have Houge,Ergo,Moe,and Moe+.Moe+ being my favorite,but would like to try the LaRue.
I have seem the frames and parts available.When Larry Vickers toured the Wilson combat factory it looked like the project was a little more labor intensive then putting on parts.But if you have the hand skills it looks very doable.Seemed like one of the biggest aspects was the slide to frame fitup.
