Choate Tool Ithaca 37 Pistol Grip M-5 Stock12 Gauge. What you do is just to install the stock on your Ithaca 37 ( M-5) and then put the forend and pistol grip on the stock. We find this setup provides much improved handling and accuracy. There is very little over-shortening of the overall length with this setup as the forend is already installed. One small screw installs the buttstock and pistol grip; no permanent modifications required to the stock are necessary. The forend is installed and the action is bleeding edge. We do this because we know that our customers will always over-build the stock and want the best. All our Ithaca 37 stocks are made from the highest quality fiberglass filled polymers. Stocks will never sag or stretch. The buttstock will always remain stiff and dependable because it is.
