Although not necessarily a tactical stock, I have/use a Remington 870 Thumbhole turkey gun. I bought the gun in 2006. About 18 months later Remington came out with the ShurShot stock. There are several pros and cons of a thumbhole. I have listed a few of each below.
- when your hand is on/in the thumbhole, your had feels "locked into" the stock, almost a part of the gun, the thumbhole fits to the hand like a cast
- a very stable and comfortable platform
- great for still and grounded/ground level targets such as deer and turkey
- specific to one sided shooter (e.g., only for right, or left handed shooters, depending on cut of stock)
- if the stock is cut for a righty, if a shot presents itself on your opposite side, the stock is not set up to be shot from the "off-hand"
- somewhat heavy
- too limiting
I am strongly considering, and would strongly suggest to others who are looking for a tactical stock to go with a pistol grip stock or ShurShot stock. Avoid a thumbhole stock. It is too limiting. I read other replies that mentioned tactical collapsible stocks such as that of the CAR 15 or other tactical weapons. I handled a Mossberg 835 Ulti-Mag Tactical Turkey gun which has a collapsible tactical stock. Although a nice gun, I did not find it all that comforitable or sturdy. I can see the benefit though of an easily adjustable length of pull. Another consideration if you are a pump gun user like myself, look for a gun or stock with an extended fore end. For example the Remington ShurShot, or Benelli Supernova. I have a shorter stature and leng of reach, so having a pump handle that reaches the receiver when the action is closed is a good thing. My final verdict: although some things can go from tactical to practical, some things belong on the battlefield, and others belong in the hunting field. To conclude, I suggest looking for something like the Benelli Steadygrip, the Remington ShurShot, or the Speedfeed III (3) pistol grip stock.
