My experience with Simmons scopes hasnt been good, I havent tried any of there handgun scopes, but I have used a couple of their rifle scopes though.
In my opinion, if your thinking of putting a scope on a handgun with any amount of recoil then save yourself some trouble and stick with the better quality scopes like Leopuld, or Buris. A Simons would probably be ok on a 22 or something like that.
