Wilson Combat has introduced the QUELL P and QUELL P-S suppressors for 9mm semi-auto pistols. The QUELL P uses a 7-baffle system to reduce sound by 34dB, measuring 6.25 inches long and weighing 9.5 ounces. The QUELL P-S has a 4-baffle system, reducing sound by 25dB in a 4.875-inch, 8-ounce design. For those who do not yet have threaded barrels on their handguns, I can highly recommend that you get into business.
