Which one are you planning on putting a scope on? <<<9mm beretta, 45 sig, 22 ruger auto, 357 colt, 38 trooper , 10mm smith>>>
A red dot sight is faster than a scope and easier on the eyes to find the dot.
Leupold, Burris and Bushnell 3200 scopes are nice.
Get a LOW power scope: 1x, 2x are about right for 99% of handgun shooting.
