A few months ago I bought a new Thompson Contender G2 14" barril in .44 mag. I am now thinking about getting a scope (or red dot) for it but don't know what to get. What kind of scope and mount is best for this gun? What features should I look for or avoid? What are the advanges and disadvantages of a red dot instead of a scope? I sometimes wonder if optics get damaged or shake loose with high-recoil calibers like this. I plan to use it for deer hunting and I don't want to spend a ton of money. Thanks!
