Anyone have info on whether/what Gray Guns parts are compatible with a regular P225 (not a P6)?  They used to list the SRT as compatible, but not anymore.  How about the strut or the enhanced leverage kit?

Thanks

The SRT is the same for the P225-A1, P229, P226.  So Grayguns should fit.  But I would call them to make sure that the P225 would use their SRT. If you have the P225-A1, it already has the SRT installed.

The Grayguns Custom Strut System will fit.  

The SIG Enhanced Leverage System will not.  The P225 uses a narrow trigger (7.5mm wide).  So the trigger provided on the ELS (9.5mm) will not fit through frame.  Also triggers are not interchangeable with the Gray Guns SIG Enhanced Leverage System so you cannot place a trigger for the P225 onto the ELS.

For an original style P225 with OEM grips, the grips may need to be modified on the inside to give enough clearance for the Gray Guns strut. See the pictures from Willard in this thread on SIGTalk.
