These are brand new OEM Sig Sauer P320 threaded barrels chambered in 9mm and made for a Compact* or Carry. We buy these directly from Sig Sauer and not a third party. Threaded barrels are used for adding suppressors or compensators to your pistol.

The thread pitch on this barrel is 13.5x1mm LH. Includes thread protector cap. No loaded chamber indicator as pictured.

Heat treated for toughness and durability.

This barrel cannot be used to convert any other caliber to 9mm (it will not convert a .357 Sig or .40 S&W to 9mm).

Note that it is not uncommon for barrels to need fitting. We recommend having a gunsmith perform this should the barrel not drop in.


*Please be aware that a P320 X-Compact is NOT the same as a P320 Compact and this barrel is NOT compatible with an X-Compact. Again, if you have a P320 X-Compact DO NOT BUY THIS BARREL - it will NOT FIT. P320 Compact and Carry guns have a 3.9" barrel. X-Compact pistols have a 3.6" (SubCompact length) barrel, but with a loaded chamber indicator not found on standard SubCompact guns.

Please also note that the P320 M18 is designated with a different name than the P320 Carry by Sig Sauer for a reason. Although there are many similarities, there are distinct differences between the two such as the loaded chamber indicator on the M18 barrel that is not present on a P320 Carry.
