Smith & Wesson M&P CoolFire Trainer Barrel

Absolutely love the product. Even though I ordered the wrong length barrel by mistake, it still fits the gun and works with my holster. This makes dry fire so incredibly close to the real thing that it makes my daily drills before shift so much more effective. Ive recommended it to everyone who does dry fire that i know, and many people from my agency have already purchased them. Love this product!
