Description
The Federal 40 S and W 175gr Syntech Defense load is built for shooters who want more from their 40 S&W than typical factory ammunition delivers. Federal loads a 175 grain segmented hollow point to a rated 1000 feet per second, producing about 389 foot-pounds of energy. Federal Syntech Defense uses a segmented hollow point that separates into three pieces plus a solid core after impact, creating several wound paths while the core keeps penetrating. It carries the same polymer jacket as Syntech Range, so it runs clean in your carry gun.

Buying ammunition by the box from the same production lot keeps velocity and point of impact consistent from one range trip to the next. Keep a record of the load you carry, check your ammunition for dents or loose bullets from time to time, and rotate your carry rounds so the ones in your firearm stay fresh. These simple habits help you get the full performance Federal builds into every cartridge.
Before you trust any new load, fire enough rounds through your firearm to confirm it feeds, fires and ejects reliably and that the point of impact matches your sights. Full-power loads produce more recoil and muzzle blast than typical range ammo, so practice with the Federal 40 S and W 175gr Syntech Defense until you are comfortable with it, and store the rest in a cool, dry place in the original box.
The .40 S&W was introduced in 1990 by Smith and Wesson and Winchester as a shorter version of the 10mm Auto that fits in 9mm-sized pistol frames. It quickly became a leading law enforcement cartridge and is still carried by many agencies and private citizens, offering more bullet weight than the 9mm with recoil that most shooters can manage well.
