One of the seldom shot pistols in my safe is an original S&W Shield in 40 cal. I really like the gun and the caliber but nowadays I enjoy shooting revolvers. I never had a lick of trouble with the Shield but I understand that the 40 cal has a less than stellar reputation. I want to give the gun to my brother, but not if he might have trouble with it. Have any of you guys had or know first hand of any trouble with these pistols? Thanks for your time.
