Unlock Your P365’s Full Potential
Upgrade your P365 with the new OEM threaded barrels, now available for X, XL, and XMACRO models. These factory barrels are thoroughly tested to provide the consistent reliability and accuracy you expect from SIG.

Major News: The $200 Tax Stamp Fee is Gone!
Did you hear? As of January 2026, the $200 federal tax stamp fee for suppressors and SBRs has been eliminated. The Form 4 (the ATF application to transfer any NFA item) paperwork remains, but the cost is $0.
Now is the time to grab the SIG SAUER MODX-9 Suppressor.
Modular Design: Configurable titanium baffles let you personalize length, weight, and sound. Class-Leading Performance: 21 points of impact adjustment for precision accuracy. Versatile: Comes with a fixed barrel spacer for carbine use.
Current eForm 4 Lead Times
While the process has historically taken many months to complete, according to the ATF, current individual eForm 4 submissions are now averaging 10–12 days.
