Pistol Thread Protector – 1/2x28 – Backup Tactical Pattern Series
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Backup Tactical Pistol Thread Protector is built to protect exposed 1/2x28 pistol barrel threads when a suppressor, compensator, or other muzzle device is not installed. These patterned thread protectors add a cleaner custom look while helping keep thread damage, dings, and bench-rash from turning a threaded barrel into an expensive little headache.

Fitment
- Fits pistol barrels with 1/2x28 RH muzzle threads.
- Commonly used on 9mm and .22LR threaded pistol barrels when the barrel uses 1/2x28 threads.
- Designed for pistol-length threaded barrels.
- Useful when no suppressor, compensator, or muzzle device is installed.
Does NOT fit
- Does not fit barrels with metric threads such as M13.5x1 LH or M13.5x1 RH.
- Does not fit 5/8x24 barrels.
- Does not fit non-threaded barrels.
- Do not order by caliber alone — verify the actual thread pitch on the barrel.
What it does
This thread protector covers exposed muzzle threads so the barrel threads are less likely to get damaged during storage, handling, range use, or transport. It also gives the pistol a finished look when a suppressor or comp is not installed.
Why it’s worth it
Threaded barrels are not cheap, and exposed threads are easy to ding up if the gun rides in a case, bag, drawer, or range box. A thread protector is cheap insurance. Not exciting, maybe — but neither is replacing a barrel because the threads got mangled like they lost a bar fight.

- Keep barrel threads clean before installation.
- Check tightness periodically, especially after range use.
Verify before you buy
- Verify your barrel thread pitch is 1/2x28 RH before ordering.
- Verify this is for a pistol-length threaded barrel, not a rifle thread protector listing.
- Choose the exact pattern and finish you want before purchase.
- Thread pitch matters more than vibes. Vibes do not stop cross-threading.
