I have installed the Graygun's dual adjust curved trigger in a Sig 229 and Sig 224 Equinox 40 with the Sig SRT kits. The pistols perform well, as far as I can tell.

I have another Sig 224 SAS 9mm with the GG dual adjust trigger installed and wanting to also add another SRT kit. Is there a significant increase in performance to be expected if I use the Grayguns SRT kit over the factory Sig SRT kit?

Hi! Good question. Our take on the SRT (which we manufacture under agreement with our friends at SIG SAUER) is a qualitative precision-machined and hand finished tool-steel upgrade to what is already an excellent kit. Our sear angle, sear face finish and engagement values are tweaked to provide a safe, dead-reliable and clean break near the lower pull weight threshold appropriate for carry and duty use, when installed with factory springs. Matched up with our competition springs and Enhanced Leverage Trigger System, you will obtain pull weights which can’t be had otherwise without compromising safety and reliability, no matter what you may hear. I hope this answers your question? If you want to try one, please message me at;

Thanks again and Merry Christmas!
