Hello all from Florida. Novice here. Can someone tell me the difference between a 38 Special MDL 60-4 BBL Stainless and a 38 Special Air Weight. Obvious lower weight, but what else. My best friend has an Air Weight 3" barrel, 5 shot which I like. Don't know if they are still available as I could not find on S&W site. If not available, other than weight, would the 60-4 be a decent alternative? I want it for self protection, small size. Thanks in advance for your comments. Dancer
