Twin Smith & Wesson 686 4” 357 magnum revolvers. The bottom one is the first gun I personally ever bought some 35+ years ago. It is the original version of the 686 from 1981 and is exactly how it came from Smith & Wesson. The top one I got a few years later and I switched out the standard wood grips for the more comfortable Pachmayr grips. Built on Smith & Wesson’s K/L frame the 686 came with adjustable rear sights.
