Our Custom Works teams hone and polish critical surfaces to lighten and smooth both the double-action and single-action trigger pull, taking your SIG SAUER to the next level without voiding the factory warranty. Includes Feed Ramp Polish. Eligible pistols: 1911, P226, P229, P220, P239, P224.


Upgrade or replace your current sights with factory-installed X-RAY3 or SIGLITE® front and rear night sights. Upgrade your aim in low-light conditions with X-RAY3 or SIGLITE® Night Sights.

Retrofit your P220, P224, P226, P227, P228, P229, P239, and P245 with the new SIG SAUER Short Reset™ (SRT) sear and safety lever parts. The SRT reduces the trigger reset travel by about 60%. This provides the shooter with the ability to execute faster, more accurate follow-up shots while maintaining a highly consistent grip and sight picture.
SHIPPING: Round trip, fully insured shipping is $55 for the first firearm and only $10 additional charge for each firearm added if you’re sending in multiple handguns for service. This would mean shipping charges on three firearms would be $75 total ($55+$10+$10). The SIG SAUER Customer Service team will email you a label, all you need to do is print it out, put it on a box with your secured firearm(s) and we handle the rest. The firearms will ship back to your address, adult signature required.
