Our newly designed (2017) P-Series Perfection Action Kit Gen2 Self Defense is like buying a Grayguns action package in a bag: custom-grade results using parts of unequaled quality, all without the added shipping expense and shop time of sending your pistol to us. Grayguns’ advanced tool-steel fire control components are precision machined and carefully heat treated for maximum durability, then hand finished, detail polished and gauged for perfect fit and function.
We’ve put our four decades of experience working on P-Series pistols for elite and high-volume shooters into our fire control components. Our Gen2 kit was carefully engineered to work together fluidly for a dead-smooth double action pull, clean single action break, positive tactile reset and minimum over travel.
Our P-Series Perfection Action Kit Gen2 Self Defense (P-PAK Gen2 SD) includes our high quality, tool-steel, Grayguns hammer and duty sear, plus our two replacement 19 pound mainsprings* and an uprated firing pin return spring. In addition to our new parts, Grayguns now has an exclusive agreement with SIG Sauer to incorporate their SRT Safety Lever with our proprietary parts to provide you an excellent short reset trigger.
Installation with factory springs typically yields a reduction in both actual and perceived double action pull weight, while maintaining single action weight appropriate for self defense or duty use.
Each part is cleverly designed to be reverse-compatible with most modern generations of factory-standard components. P-PAK Gen2 SD is a serious, practical upgrade designed to withstand the hardest duty use and high volume training.
Order your choice of trigger to our Perfection Action Kit. Select from our P-Series Precision Adjustable Intermediate Trigger – which is found in all first-generation SIG Sauer Legion DA/SA pistols – or our P-Series Precision Adjustable Straight Trigger which is available in Alloy Steel or Aluminum versions. (We do offer a limited selection of aluminum triggers in color.)
Our P-PAK Gen2 SD fits modern DA/SA SIG Sauer P-Series pistols including the P220*, P228, P226, P226 X-Five Allround, P227 and most obsolete versions.
The P-PAK Gen2 SD does not fit the following:
- *Early P220 pistols with the classic narrow trigger or spur hammer.
- P225/P6, P225A1 or P239.
- SIG pistols with DAK or DAO triggers.
- Browning BDA pistols
Check with Grayguns if you have questions about compatibility.
* We provide a second, 19 pound mainspring to ensure reliability through proper maintenance. We recommend changing mainsprings at 5,000 cycles.
