OK, quick background. I'm 62, been shooting since I was 7. Retired California Highway Patrol officer. When I started on the job I shot a Colt Trooper MkIII .357 with 6" barrel.

I plan on starting to shoot some USPSA coming this January. While I love the 1911, I'm also a revolver guy at heart and thought it would be fun to shoot a revolver instead of the 1911 as everybody seems to shoot the 1911, so just bought a 6", 6-shot, 586. I have a bad back, intestinal problems, so I'm over weight and out of shape, so I don't plan on being a champion on any level.

I plan on shooting the stock revolver for a long time, but I'm sure there will be things that I might like better if they were modified. Just curious what types of modifications, if any, I should look at and research for somewhere in the future? I don't even have the gun yet, so I know it will take some time to break in, so not looking for anything to do immediately, just curious about what types of things to plan on in the future so I can talk to my gunsmith and see costs, etc.
Thanks in advance
