I agree with the Titebond choice. I have usually been able to hide any dowel reinforcement by removing the tang and drilling a hole in that area to hide it under the tang or through the trigger guard. The way I do it,is to first glue the crack up and get it all lined up and clamped. After that is well set in a day or two, then I drill through the areas I said, to install the pins. My personal choice is wood pins, so it has the same expansion and contraction rate as the rest of the stock. Be sure to cut some grooves in the wood dowels so that the pressure of inserting the pins does not hydraulic the crack back open. Others like metal pins. There you can use a piece of bolt or all thread as the threads will allow for the hydraulic pressure to relieve itself. These are the 2 ways I am familiar with and like I said, my personal choice is the wood dowels. I will do anything to hide the fact that the stock has been cracked and so far I have got away with it. There are other ways that work well for others though.
