Unless you take off that butt plate and shave some from your stock you are going to get increased length of pull with ANY recoil reduction pad. They don't add THAT much length, well MOST don't, but if you are at that "sweet spot" with what you have then you will need to shave a bit off to keep it at a length you like. If you don't want to do any shaving then you will just need to adjust your position to compensate for the added length. The Limbsaver pad that you install, not the slip on, after taking the original butt plate, will add about an inch to the original pull. Not that significant.
