34260221-R
TRIGGER-BAR-2
1200637-R

They seem the same except for the finish, which is the one Sig puts in the gun from the factory?

I did not look them all up, but a simple Google search of the last two numbers showed different finishes.

Hey Jimbo!! Don't know about SIG trigger bar part numbers, but thought I should mention that SIG 'P' gun trigger bars don't share GLOCK's 'connector' modification abilities.

While installing a 3.5lb connector in your Glock is an easy/cheap trigger job - mods to a SIG trigger bar is the fastest way to screw-up these pistols. Even slight changes to a SIG's trigger bar's control surfaces can change it's timing - and the gun may no longer cycle!!

Just a friendly heads up that these trigger bars are a part I don't mess with...

Cheers

A couple of them have different finishes. I looked here:

Looking at Top Gun Supply, Midwest Gun Works, Numrich and Brownells; the descriptions vary but there are some clues (see blue text above).

Depending on the production time frame and the model pistol, I'd say SIG puts/has put all of these in pistols from the factory. My guess would be that the 1200637 (Phosphate) is for the M11A1 and MK25 and any other model requiring phosphated internals. I'd also guess based on what I've seen recently that the 1200332 (Super Finish) is what's being used in current production. Beyond that, I don't know, but I think any one of them will work in the 226/8/9.

That was my thought exactly, any one will work.

I would opt for the Super Finish version if it's available. From what I've seen, it's smoother and better finished. JMHO.

I thought so too, but the Super Finish one is a little different than the TRIGGER-BAR-2 in terms of geometry. In fact I tried installing a Super Finish one in an older p229 (US made) and it does not fit, with its old trigger bar looking much more like TRIGGER-BAR-2. The differences are in the area that engages with the hammer and sear, but because of that difference it does not allow the disconnect tab to go down sufficiently for the slide to move properly

EDIT: I checked recently and the Super Finish trigger bar is what is used on my Legion p229. That implies that the parts/frame around where the back of the trigger bar engages with hammer and sear are different, i.e. not just specially treated/coated p229 parts but a different geometry... I am not willing to take the two guns apart again enough to investigate that difference, but if someone were to do it, I would be very curious what the findings are.
