If you want it for hunting the get the S&W 610
Good point from deadeye. OP, what will be your main purpose for having the 10? Would you be using it for hunting or just having one for personal use and protection. If it is hunting, you may want to go revolver and heavier round for longer shots. If it is for personal use and protection, against man or beast, then Glock in that G20 is fine. Just know that it is a big gun compared to the .40, yes even the SF is beefier, but you want that in the 10mm cartridge.
If you do get the Glock, get the trigger connector to take it down a few pounds of pull.
