Bottom line for me is if the gun doesn't fit & hit correctly for POI, what good is it. Basically, it comes down to you need to do, what you need to do to get the gun to work for you. Another option not discussed is to leave the gun the way it is and use a slip-on pad to extend the LOP.
As far as extensions goes it wouldn't make a difference to me one way or another, either direction you go, it will always be seen and if you decide to sell the gun in the future an extension could be a deal breaker to a potential buyer. I know it would be for me!
