      Recoil with the M29, stiff but controllable.

      “Magnum mania” was now sweeping the handgun world and it seemed that everyone with R&D or production facilities was either trying to develop a new magnum cartridge or market a revolver chambered for one. In 1963 S&W had announced a new N-frame, the Model 57, chambered for the .41 Remington Magnum cartridge, which was intended to provide sufficient power for hunting big game but with lower levels of recoil than the big .44. The following year, in an attempt to popularize the .41 Magnum with police, S&W introduced the Model 58 revolver which, with its 4-inch heavy barrel and fixed sights, harked back to the .44 Hand Ejector Third Model. Despite the development of medium-velocity .41 Magnum loads, the concept never quite caught on with American police although a loyal group of big game hunters evolved that kept the .41 Magnum cartridge and Model 57 revolver commercially viable propositions.

      The next trendsetting move by S&W occurred in 1963 with the introduction of the J-frame Model 60, the first all-stainless steel revolver. As the practicality - and popularity - of stainless steel grew, S&W expanded the option to most of their N-frame guns. Over the next several years, the market saw the introduction of the stainless steel Models 629 (.44 Magnum), 657 (.41 Magnum), 624 (.44 Special), 627 (.357 Magnum), 625 (.45 ACP) and 610 (10mm Auto). The two latter guns use full moon clips to handle the rimless pistol cartridges and, because of their rapid reloading capabilites, once dominated dominate those action shooting sports where revolvers are used such as ICORE, bowling pin shooting, IDPA and IPSC.

      With the burgeoning popularity of semiauto pistols, in recent years the market for revolvers has shrunk, leading to S&W’s dropping several models. But that being said, over the past few years S&W’s Performance Center has introduced a number of limited edition and custom N-frame revolvers. Six of the newest are the Model 625 5.25-inch competition revolver in .45 ACP; the classically styled, blue steel Model 251 .45 Hand Ejector in .45 Colt; the Model 28 in .357 Magnum (an eight-shooter, no less!); the Heritage Model 25-12, a reincarnation of the Model 1917 in .45 ACP; and two tricked-out hunting revolvers, the Model 647 Comped Hunter in .41 Magnum and Model 629 7.5- inch Stealth Hunter in .44 Magnum.

      The newest kids on the block are the S&W Night Guard revolvers, which utilize a frame constructed from a special alloy that contains a small amount of Scandium, a rare metal that has the ability to transmit its strength and flexibility when alloyed with other metals - in the case of the Night Guard revolvers, aluminum. This allows the construction of lightweight frames capable of standing up to the operating pressures of magnum cartridges. But the Night Guards differ from S&W’s other light weight revolvers in that a replaceable blast shield made of thin, hardened steel is positioned above the cylinder/barrel gap where it prevents hot powder gases from “cutting” the frame’s top strap. While it would have been possible to use titanium cylinders to reduce weight even further, S&W decided to fit the new revolvers with stainless steel cylinders featuring a Physical Vapor Deposit (PVD) matte black finish that provides increased protection against salts, solvents, powder residue, abrasion and just about any other problem they may encounter.

      Night Guards also feature what just might be the most practical set of sights I have ever seen on revolvers intended for service use. The XS Sight Systems 24/7 Big Dot front sight has a tritium insert surrounded by a large, white ring making it equally visible in the dark or bright light conditions. The rear sight is a Cylinder & Slide Extreme Duty fixed unit whose generously-proportioned U notch allows a fast sight picture and alignment under a variety of light conditions.

      The Night Guard line includes three N-frame guns: the M327NG (eight shot .357), M329NG (.44 Mag) and the M325NG (.45 ACP). As it would be unprofessional of me to pass judgement upon these handguns without actually test firing them, I amassed a varied selection of N-frame revolvers and my friend Butch Simpson and I ran them through their paces. My test guns ran the gamut from oldest to newest: a British contract .455 Triple Lock (converted to .45 Auto Rim, and so marked on the left side of the barrel but restored by the present owner with an original .455 cylinder; a .357 Highway Patrolman; a .44 Magnum Model 29; and a Performance Center Model 625 5.25-incher. The intended purposes of these four handguns run the gamut from military service (Triple Lock*), to big game hunting (M29), to action pistol competition (M625) and, finally, to police service (Highway Patrolman). Test ammo consisted of the following: Federal .357 Magnum, 158-gr. Nyclad; PMC .44 Magnum, 180-gr. JHP;. Lawman .45 ACP, 230-gr. FMJ; and Fiocchi .455 Mk. II, 262-gr. LRN. Ably assisted by my good friend Butch Simpson, I fired each gun for accuracy from a rest at 50 feet.
