Smith and Wesson?s first true venture into the synthetic pistol realm was in 1994 when they created the Sigma pistol but if never really took the market by storm. Many shooters complained of the heavy trigger and long reset.? Then S&W introduced the M&P (Military & Police) series of semi-automatic handguns in the summer of 2005.? In this author?s opinion it was their first ?real? attempt to delve into the polymer pistol market. It utilizes the time tested titling linkless cam, short recoil operation designed by the illustrious John Browning. As the M&P has been out for a little over a decade now S&W has release numerous differing models; with the full size guns having a 4.25? barrel and a Pro Series model with an extended barrel for competition. Well, as always with the competitive shooting crowd there are always more changes to be made, accessories to be added, and customization to take place.

One of the most common changes made to a firearm intended to be a competitive gun are the sights or the addition of optics. Well, S&W was listening to their customers and on November 7th, 2012. S&W announced that 4 new models had been added to their line of M&P pistols. They introduced their C.O.R.E. line of M&P pistols in both 9mm Parabellum and .40 S&W with barrel lengths of 5 and 4.25 inches. The acronym C.O.R.E. stands for Competition Optics Ready Equipment and features a removable section of the slide just in front of the rear sight. The firearm can be fitted with the desired optic through

the use of removable brackets and it is designed to work in conjunction with the Trijicon RMR ?, C-More STS, Leupold? DeltaPointTM, Docter, Insight? ?MRDSTM, and JPointTM red-dot sights (RDS). 1

Furthermore, for improved performance, the M&P C.O.R.E. pistols come standard with a Performance Center sear which allows for a crisp 4.5 pound trigger pull and a shortened reset between shots when compared to the standard M&P line of pistols. S&W also added higher sights so that the shooter can co-witness the iron sights along with the red dot. This way if the RDS fails for any reason the shooter can continue with the competition with the use of the raised iron sights. Also, S&W offers this model with a crowned muzzle for better protection of the rifling and improved accuracy. All of the standard features of the M&P are still standard on the C.O.R.E. models such as: 3 interchangeable size backstraps (but with a new design and texture meant to be more aggressive), a polymer frame with a Melonite? ?finished hardened stainless steel slide and barrel, ambidextrous controls, a stainless steel internal chassis, a passive trigger safety, a witness hole loaded chamber indicator, scalloped sear cocking serrations, & a simple takedown lever with a sear release lever for easy disassembly.1

The model tested for this review is the 4.25? .40 S&W model fitted with a Trijicon RMR ? adjustable LED2 RM06 with a 3.5 MOA Red dot. Trijicon has proven that there products are rugged and hold their zero with had use for years. The adjustable LED allows the operator to adjusted the intensity of the dot depending on ambient lighting. In a very bright environment the shooter can brighten the dot and in low like conditions the dot can be dulled. This worked quite well at the range.

The range session was conducted utilizing a selection of ammunition with included Winchester 165 grain FMJ, Federal 180 grain FMJ, & Fiocchi 170 grain FMJTC (truncated cone). All ammo performed flawlessly at the range. And the gun never malfunctioned once during a 500 round range session. However, at a around 150 rounds the Trijicon began failing. Upon recoil the dot would deactivate and could not be turned back on. I decided to continue the review with the iron sights, this is where co-witnessing the iron sights pays off. Well, upon firing again the red dot turned back on during recoil. That is when I noticed that the left allen screw had walked out during the shooting session. I cleared the firearm and reached in my range bag; it is always good to keep tools with you at the range. I removed the screw and added a bit of blue Locktite ? threadlocker and tightened the screw back down. The dot never failed again after tightening the screw back down.

The accuracy was quite good! The first target below was shot with the Winchester 165 grain FMJ loading at 15 yards in a controlled manner. The second target below was shot with the same load but as fast as I could acquire the red dot in my vision; pulling the trigger as quickly as possible. The gun is truly set up for a USPSA Match so that?s just what I did. I entered the match nearest to me and figured I?d see how the gun and I would perform under stress.

For the match I utilized A Blackhawk ? Sportster ? , I like the trigger guard retention but the lack of a manual release such as a button or thumb break. It makes for a fast clean draw and the low top end of the holster more than clears the optics. Furthermore, due to the optics, the worth of this gun would be decided in an Open match. First off, 3 malfunctions were experienced during the match and they were determined to be from a new faulty magazine that hadn?t been tested before the match. Once, that magazine was discarded the gun performed wonderfully and the RDS made acquiring a sight picture quite fast.

All in all, I think that this gun will prove to be a formidable contender in a production gun that can handle itself with the high dollar guns normally seen at these kinds of events. So, for a great price you too can enter a new world of competition with a reliable, accurate, and might I add decent looking firearm.
