What kind of competition are you looking into? IDPA? USPSA? NRA? Bianchi? ICORE? Steel Challenge? Silhouette?

How much money do you have to spend?

Are you going to reload? This is a factor, my SVI doesn't like factory length 40 ammo and I have to load it to 10mm length. Also, some calibers are prohibitively expensive if you don't reload, 38 Super is one.
