I have been Jones'ing for a Ruger Mk IV Competition for a while now, as I love the long barrel and the accuracy reports I have read about. I checked one out this weekend (couldn't shoot it unfortunately), and the wooden grips with the thumb support felt AWFUL in my hands. I could not get a good weak hand grip no matter how I tried. It was the most uncomfortable grip I have ever seen. So what is the deal here with those that have this gun with that large wooden grip with the thumb support? Is there a special way to hold it that I am missing? How have you been able to "come to grips" )) with this design? What about aftermarket replacements? I am considering using this gun in Steel Challenge matches as well as a gun for my wife to plink around with. Thanks for any help/advice!
