If you want a 9mm muzzle brake for your sidearm you could buy one from just about any manufacturer who offers pistol muzzle brakes, but do you really want to? When it comes down to it do you want to buy your muzzle device from someone who makes a little of everything, or would you do better to buy from a manufacturer who specialized in the manufacture of quality muzzle devices? When you’re in the market for a quality 9mm muzzle brake as well as other pistol calibers, choose the Rex Silentium TriDelta Tactical Pistol Muzzle Brake and you’ll never regret the purchase.

Rex Silentium offers their pistol muzzle brakes with either standard or metric mounting threads so that you can apply one to almost any manufacturer’s handgun without a lot of preamble. The Rex Silentium TriDelta Pistol Muzzle Brake will not interfere with the use of sights. The TriDelta brake was carefully designed, not only is muzzle blast and recoil managed, but the brake has no six-o’clock pots so dust printing is not an issue when shooting with these brakes in prone position.

While many of today’s muzzle brakes claim to master recoil forces, the Custom Muzzle Brakes TriDelta pistol muzzle brake uses the proven TriDelta baffle design to direct concussion forces and muzzle blast away from the operator. With a TriDelta pistol muzzle brake installed you’ll have better control of your weapon for better accuracy. Muzzle rise and recoil become more manageable and you’ll waste less time on target acquisition. That means your follow-up shots will be faster and more accurate than those of your competitors who use inferior 9mm muzzle brakes or go without a muzzle device. You’ll be faster and more accurate than the competition before you even start shooting.
