Incredibly versatile, the JK 155 VERSAX .45CAL is ideal for 9mm, 10mm, 40 S&W, and 45 ACP pistols and is one of the lightest pistol suppressors on the market! At the same time, it’s stout enough for full-auto use on 300 BLK, 458 SOCOM, and many more, and for sporting use on 44 Mag, 45 Colt, and 45-70 Gov’t on up to 300 Win Mag.
