Bought a LNIB 686-5 (4 inch) from a friend about 6 months ago. Great shooter! Also NIB 442 snubby in May as my EDC. Love it! Several hundred rounds so far with zero problems. Most recently a S&W MP 2.0 in 9mm because a wanted a higher capacity 9 mm semi for my "House" gun than the SA XDS that I have. I really love all of these, plus the 620 SW I bought several years ago, and I have had zero problems with any of my S&W guns.
