So I have some gun money burning a hole in my pocket. I have Owned many guns over the years and I want something different this time. I ran across a smith 4" 500 mag and I just gotta have it. I have shot 454 casuls but doing you YouTube searching the 500s have quite a bit more power. I don't want one with an 8 in barrel. What is a good price for a 4". What is the interchangeable thing on the barrel. What have u shot with yours? Any pics? How accurate are they and is the recoil that bad? Anyone know of one for sale?
