I like the mossberg 500 my dad own one and both of my brothers own one,i probably would if i didnt already have an 835.no experience with the tikkas but from what i have heard they are a superb firearm
I've got a 500 slug gun for hunting in MD. I love it, have taken several deer with it. I do understand the "flimsy" comment made. I thought the same thing when I bought it. I have two 870's and they do feel more solid, but I've never had a problem with the 500.
I have both mossberg 500 and a 870 express. IMO they are very close to the same. The Remington just costs more. If your were to buy the 870 Wingmaster that changes everything. Entirely different gun IMO.
