The original stock Works really nice for general use. If your money is as hard to come by as it is for me, my recommendation would be to upgrade the rifle's action- trigger, hammer, sear, springs, etc.- and leave the stock for last. Believe me, ANY rifle will have the "intimidation" look in a defense situation regardless of the look of the stock. Matter of fact, the very sound of a pump shotgun chambering a round is more intimidating than the look of any stock.
If you must have a stock, look at the offerings of www.cheaperthandirt.com. They have a section dedicated to 10/22's.
