ACW 1/2x28 low-profile thread protector is precision machined from 321 stainless steel and Melonite coated for increased durability and greater heat resistance. The significant advantage with this low-profile thread cap is that the barrel can be removed or inserted without removing the thread protector. Made to fit any 9mm/357SIG/22LR threaded barrel with the common 1/2-28 threads. Pistol brands include: Glock, S&W, HK, Walther, Ruger, Sig Sauer, Beretta, Springfield, etc. Please bare in mind that it will not fit any other threads other than 1/2-28 RH (factory Glock threaded are not 1/2-28).
