It’s small – real small, folks – and also extremely light. Smith & Wesson Model 37 Airweight: My first thought was, like, “Whoa…” I happened to get my hands on one of these cool little revolvers. If you are familiar with this particular firearm, then you know how many other models are similar, if not almost identical, to the Model 37. The pistol in question for today’s review is the Airweight. I have always been a Smith & Wesson fan, especially for their handguns – from the tiniest J-frame pistols to Dirty Harry’s Model 29, Smith & Wesson delivers, and delivers well.
