I am new to hand guns but now I am smitten. I shot my first hand gun in 30 years last February and now have developed a deep interest in them. OK, I want to buy as many revolvers and semi-automatic pistols as I can before I die. (Wife rolls her eyes.) My first purchase is going to be a Ruger GP-100 revolver. My interest, however, goes further than the basics of hand gun safety, handling, maintenance and shooting techniques. I am interested in learning how these weapons are designed and manufactured, from the design drawings and factors influencing various tradeoff decisions, the metallurgy and casting to the manufacturing steps. The physics and engineering of fluid dynamics and internal ballistics would not be intimidating. It's the art of the design of these weapons I am fascinated with. I don't think a typical gun manufacturer, however, is going to trip over themselves to reveal anything proprietary, I realize that. But might there be some books or articles out there that address these subjects? Typical google searches turn up gun encyclopedias, gun digests, gun catalogs and an occasional ballistics treatise on rifles, howitzers and mortars. Just the hand gun please. Any suggestions?
