The Night Guard line includes all of the other innovations that S&W has made to its revolvers in the last few years. It has a frame-mounted, spring-loaded firing pin; smooth trigger; checkered hammer; and a two-part barrel consisting of a rifled inner steel tube covered by an alloy shroud that permits the barrel to be mounted in the frame without exerting undue stress on the frame. Lastly, they all have S&W's key-operated Internal Security Lock, which can be used to prevent unauthorized firing.
While the Night Guard line is extensive, for POLICE Magazine I tested the one that I feel is the most practical of the bunch for concealed or off-duty carry, the Model 315NG.
The 315NG I received impressed me immediately. The fit, finish, and the quality of materials were what you would expect from the world's premier revolver manufacturer. While the trigger pull was a bit on the heavy side, backing off the mainspring adjustment screw a few turns made a noticeable difference without compromising cartridge ignition.
Even though it was a hot, humid afternoon I was anxious to see how the new Smith performed. Gathering together a selection of .38 Special ammunition I headed out to my gun club to see if the 315NG is accurate and reliable enough for a personal defense weapon.
The first chore was to ascertain what kind of accuracy could be produced firing it from an MTM Predator rest at 15 yards.
All four brands of ammo that I shot in this test produced more than acceptable groups and printed close enough to point of aim to please me. It should be noted that the sights appeared to be regulated for 158-grain ammo as these printed dead on to point of aim while the lighter, faster bullets grouped low.
After chronographing the four brands of ammo, I set up a pair of combat targets, belted on a Safariland holster, and ran the Smith through a series of drills at seven yards, firing the revolver with both supported and unsupported (one-handed) grips. Despite the 315NG's light weight, recoil control was excellent—helped in large part by the tacky Pachmayr grips—and it proved no problem at all to make fast, accurate follow-up shots. The sights provided fast target acquisition and easy transitioning.
To my way of thinking, Night Guard revolvers may be the driving force behind a renaissance of the medium frame wheelgun's popularity with police in this country. The K and L frame guns in particular would be equally adaptable for concealed carry by undercover officers or as off-duty/backup guns in those jurisdictions where carrying such weapons is permitted.
