Bought a set of grips awhile back to go on my 4" King Cobra, and finally got around to "doing". I took off the pachmayers, and the new wood grips did not fit AT ALL. I noticed some evidence from a grinder of some sort on the left side of the butt. Curious, along with not overly happy, I took off the grips on my 6" King Cobra too. I am not sure how to describe this situation. The 4" butt frame (??) is not even-it is "offset" The 6" is even. I'll attach some pics and hopefully it shows up well enough. I have no idea how I can get grips for this 4", but I am guessing one of the previous owners had trouble getting grips to fit also, considering the grinding. Is this butt normal??
