Specifically on the Grayguns SRT Kit, Strut System, Leverage System. Are they upgrades and show improvements/benefits when installed on Legion pistols? Anyone have any experience?

The ELS is a great upgrade for the Legion, well worth it.

The strut system is one of those things that you don't think you need until you use it. I've never noticed any issues with the stock DA pull in any of my P-series, but if you buy the strut system if only as a bag of spare parts, you'll then notice the difference once installed. I personally don't have one in my Legion, but I will one day, as I really appreciate what it has done for my other P-series.

I personally prefer the Sig SRT over the Gray, but I think that's only because I'm been pulling triggers with the Sig version since it was invented. Others probably prefer the Gray, and I can understand why. For most, I doubt there's a discernible difference. Since your Legion has a SRT, I'd only get the Gray if you're bored and have extra cash to support a great company.

I've also had Grayguns put the ELS system into my P229 Legion and P226 Legion - and have also added the P-series custom Strut system as well. For me, it added significant smoothness, speed, and reliability. Grayguns makes great products, and their Chief Gunsmith Keith Hosey is the best - superb customer service every time I've emailed or spoken with him.

The only Sig parts of the trigger and hammer group is the SRT on mine.
I used the first style ELS with the strut and 19# spring.
I use Armory Craft hammers as well.


I have the ELS in my 229's with TSA Superstrut and 20# spring.

I can’t speak to the Legion specifically, but they completely transformed my MK25 Navy and P229ST. I have a P220ST with a Sig action job and a P228 that was worked over by Bruce and company shortly after their move to Oregon. The two pistols that I used GGI drop in parts have better actions than the ones worked on by pro gunsmiths. I just ordered another SRT kit and fat strut kit for a classic P226ST because of how good my past results have been.
