Anyone know if the Grayguns SRT is substantially better than the regular Sig SRT?

interesting question...I'd like to hear as well. I am going to guess and say they are similar!

I would be interested in a comparison, also.
I am looking at an older used P series without the factory SRT.

As there have been no useful responses yet, I’ll offer what I vaguely remember from when the factory SRT mod was introduced some time after the Grayguns version.

What I recall was that although the two versions were very similar, users somewhat preferred the Grayguns SRT mod as having better trigger pull characteristics. A little lighter, a little smoother? I don’t recall other than that those could have been the impressions.

I'll echo what Sigfreund said. When I did my 229, I went for the Sig SRT only because I was having them do some other work anyway. However, I vaguely remember folks saying that the Grayguns version was actually better.

The biggest difference is that the GGI SRT allows the Firing Pin Block to reset between shots while the factory SRT does not

What does that mean?

I'm not sure how else to explain it.

Let me try this.
With the factory SRT installed, the Firing Pin Block does not impede the firing pin's travel between shots when you avail yourself of the shorter reset.

That is why early factory SRT modded pistols would sometimes double...until the factory increased engagement of the sear surfaces

The purpose of the firing pin block (the “safety lock” in SIG parts talk) is to … block the firing pin’s movement forward to strike the cartridge primer unless the trigger is pulled. The safety lock is pushed out of the way of the firing pin by the “safety lever” that’s connected to the trigger bar. When the trigger resets in the non-SRT mechanism, the safety lever moves back down, and that allows the safety lock to again block the firing pin.

The factory SRT mechanism, however, evidently does not permit the safety lock to move into its blocking position between shots. I’m not absolutely certain what “between shots” means, but it must have something to do with not resetting to the blocking position when the gun is cocked for the single action mode. Once the hammer is decocked, however, the safety lock evidently goes back to where it normally rests.

That makes sense, as my 229 did in fact double at first, and I had to send it back. Works fine now. I guess that's another prop for Grayguns.

Not to take away from what sigfreund said, however I have both GGI and SIG SRT's and the functionality, as far as I can determine, is the same.

The only difference between the two SRT kits is that GGI's kit includes a machined tool steel sear, while the factory SRT sear is a MIM part.

The dimensional tolerances on the GGI sear are quite precise, while I've measures variation on the MIM part as much as 0.0025". This translates to the likelihood of better trigger feel, though there's no guarantee of that if the hammer is MIM.

Both SRT kits use the same OEM safety lever, so there should be no difference in safety block plunger lift.

BTW, the safety block plunger has nothing to do with "doubling", it is there to block the firing pin channel until and unless the trigger is pulled to near its rearward travel. This causes the safety lever to push upward on the plunger to unblock the firing pin. This to prevent drop or inertia firing as well as an additional safety against letting the hammer slip and fall etc.
