Greetings, haven't been on since the '05 version of the forum

the following relates to a possible near term purchase, longer term project.
Shop in walking distance of me has a rather nice used model 12 variant (Barrel says "12 Long Range" can't find a current listing) in an HS precision stock that I assume has the factory standard Length of pull of 13.5".
If we buy it this rifle would be for my wife, and using the "fast and dirty LOP check"(butt in elbow crook, can index finger reach trigger?) method, the stock is about 1/4-1/2" too long.

Now the question is, Just how much of a pain is it to, pull the recoil pad, trim 1/2" off the stock body, and then reattach the pad? or is this even possible?

I know that I can order a new stock with the shorter LOP but I figured i'd inquire as to the difficulty/possibility so as to save $350-400 depending on timing sales etc.

as always thank you for your time and any info you care to share.
