Sig SRT vs OEM objective trigger test- P227

[saki302]

I'm surprised no one has done this yet, so here it is.

I tested my stock P227 trigger vs. the SRT it came with.

Here are the results: (trigger travel measured from the bottom TIP of the trigger).

Stock/SRT DA trigger:
10lbs 14oz (nearly pegs my gauge)

Stock SA trigger:

7mm take-up (1lb 12oz)

5lb break
2.5mm break travel (some overtravel)
3mm reset (fairly soft reset for a pistol- standard Sig reset)

SRT SA trigger:

Same take-up specs

4lb 6oz break (this surprised me, I'd swear it broke heavier)
3-3.5mm break (noticeable overtravel- trigger also has more creep)
3-3.5mm reset (positive 'click')

The thing you will notice about the SRT is the reset is EXACTLY where the trigger breaks. You can pull back right when you feel the click, and it will stop and go bang. The stock trigger has about 1/2 a mm of
'flop' between the soft reset click and where the trigger stops. I can see why people would shoot faster with the SRT.

With either trigger the P227 has a lot more overtravel vs. my old German P220s. The P220's frame geometry has the trigger staging more to the rear and stopping with less overtravel, which I like more. I'm going to look into the Gray's guns trigger which has a built in overtravel stop. I'm assuming it will take filing to get it set how you want it. The SRT with overtravel stop is going to be something special, I think.

Thanks for this info. Recently aquirred a 227 Equinox. I enjoy the gun. Shoot SA well and DA reasonably well.

The one drawback is the trigger travel before the SA break. Would be interested to know if the Gray Guns trigger will fix that.

Thanks! I picked up a P227 Carry Nitron recently - would love to hear more about the Gray trigger if you end up getting it.

Had a discussion about the Short trigger when I swapped one into my DAK.
The angle of it vs stock trigger seems to reduce leverage.
Pull wright difference is negligible, but on a DAK you can really feel the short trigger's inefficiency in your wrist.

I have the Gray P-SPIT trigger installed in a newer P220 Combat.

I had Sig do the SRT, and it works well, but the overtravel did feel exaggerated especially with the short reach trigger. The Gray trigger fixed that issue and I also prefer the reach and feel of it vs the factory short reach, which in my opinion is a little too short for my medium sized hands and the 220 anyway. So I just wanted to report it is a good combination and a well-made part too.

I sent my gun to Grayguns, and they also put in their extactor and did some action tweaking and polishing. Very happy with the work, but if I was doing it again I would consider just installing the trigger myself, I think fitting would be minimal if any. I am now much more familiar with the internal workings than I was at the time.

I am on Gray's notification list when their trigger comes back in stock

I'm tempted to tack on a pencil eraser with double sided tape behind the trigger just to test how well an overtravel stop would work. I suspect it will substantially cut the overtravel and reset on the SRT.

I'm surprised no one makes a trigger with screw overtravel adjustment. Use a screw with a polymer tip if you don't want to mark the frame (Sig triggers mark the frame anyways).

UPDATE:

I was bored, so I bought some set screws with polymer tips and a spare trigger and made an adjustable trigger stop.

It works just as expected- the trigger has about 1.3mm movement to release in single action mode after take-up, and 1.3mm reset.

Should be MUCH faster, and the large amount of overtravel is gone.

We'll see how it shoots Friday

I hated the SA reset on my 226 Mk.25 until I installed an SRT.

All my sigs have the SRT huge upgrade.

Appreciate the info on this. I just took my p227 out for the first time yesterday and compared it stock vs my p226 with standard fat trigger and SRT.

Came home immediately and ordered all the parts to upgrade the p227. I was actually getting alot of pinching in index finger with the p227's skinny trigger (as well as noticed the longer reset). Hoping my upgrades will make the trigger more comfortable to shoot. I'll keep you guys posted after both parts are installed.

Put the SRT on my 229. Well worth it imo.

Can you buy just the trigger by itself from GrayGuns? That is honestly all I need, I don't need the polishing and other work simply due to the fact that if something goes wrong I can always put the stock trigger back and send it in for warranty svc.

[saki302]

Pistol shot GREAT- works perfect now. SA pull feels kind of like a non-match 1911 (pull and reset length).

As far as Grays goes- they do sell just the trigger but it requires fitting, and they're currently out of stock.

Put the SRT in my p226 9mm few months back! Saturday I ran her through a pistol 1 class and we were practicing rapid fire using reset, the instructor commented that my pistol sounded like a full auto, it was so freaking beautiful dumping mags into the target! That trigger is a must, hands down! Love my stock walther ppQ trigger reset as well, but never ran her through a class...yet!
