how about a used gun for a beginner. How would a novice know weather a gun has already been modified to another shooter when he-she mounts it and it feels good. Would it be wise to get it checked out somehow to see if its gonna cost more to recorrect than if you bought a new gun in the first place. I'm seeing anywhere from short of $100.00 to maybe more than $500.00 to get a proper fit. When I bought my gun from a local gun shop ( well known here in DE) the sales person, whom I suspect had something to do with ownership, did give me some good advice and helped me select a Browning Citori O/U that was about 7 years old as opposed to a new gun. I saved about $500.00 and am just about to shoot it in the next week or two. I'm hoping its as close as it needs to be to be happy. I'm now a little worried it might be off some and won't know if its me getting used to a new gun or if some modifications are causing me problems. I'm gonna use it mostly for sporting clays. Just from reading posts I'm seeing the importance of slight modifications. I'm a bowler and I know how little things mean alot.
