Have shot several Desert Eagles... and have also shot the Alaskan Guide Bear Gun from Cabelas... both are 50 cal... don't think that is what I am looking for. I have debated about lenght of barrel though. I have been told you will have more force on impact with a longer barrel. I don't need, or want to conceal the weapon, I just need to wear it on my chest to keep it out of the water. That is why I have been looking at a tactical. It has a longer barrel, and according to people who have shot the weapon, has a larger grip. I have very big hands and will need a larger grip to fit.
