Finishes
Black Oxide
- Standard blued finish
Titanium Nitride (TiN)
A well-proven standard layer type through its balanced properties. The golden titanium nitride layer, abbreviated TiN, indicates the following properties:
- High hardness and adhesion
- Good chemical resistance
- Good temperature resistance in air
- Relatively low thermal conductivity
- Attractive, golden color
Titanium Carbo-Nitride (TiCN) (Copper)
The TiCN Copper finish features high hardness, low residual stress, good abrasive wear resistance, and high reliability in dry operations.
Physical Vapor Deposition (PVD)
This state-of-the-art process creates a molecular bond to the trigger, resulting in a durable finish. The PVD finish should not rust, discolor or tarnish.
Nickel PTFE
Electroless Nickel PTFE (Teflon®) is an advanced, self-lubricating, composite coating with PTFE particles co-deposited in the electroless nickel layer. Provides a hard, uniform, self-lubricating coating for our premium aftermarket triggers.
Dual Adjustable Straight Trigger Fit Guide
The trigger is designed to fit both current and older model traditional double-action (DA/SA/decocker) P-Series pistols, including
- X5 All-Round

The trigger is incompatible with our trigger bars included with the Enhanced Leverage System.
These triggers are approximately 10mm wide. At this time, we are not suggesting this trigger for guns equipped with the DAK trigger system.
This trigger may not be fully compatible with California-compliant or similar P-Series pistol models equipped with a magazine disconnector, and Grayguns urges caution. We do not recommend deactivating any mechanical safety device.
The Grayguns DA/SA triggers will not fit SIG Pro, P225 / P6, P239, West German P220s, or most SAO models. Most of these triggers are a narrower 8mm width.

An excellent upgrade to my Sig M11 A1. The trigger is much improved in DA and SA. Also, the customer service, communication, etc. was second to none. I’m very happy.
I prefer a flat trigger and after looking around decided to go with the GG version. The trigger first arrived with the trigger pin hole a little too tight and it wouldn’t allow the trigger to reset. Customer service (Chris) had me send it back to them (postage paid) for adjustment. The turn around was very quick and the trigger functions properly now. I love how the pre travel (which seemed significant on my P229) was eliminated and the trigger feels great. I would love to see an upgraded trigger bar that works with this trigger so you wouldn’t have to buy the whole kit after you already have the adjustable trigger. Overall I am very happy with the experience.
Thanks GG
TiCn looks great. Install is fairy easy. Takes a little time to tune it right. Worth the $.
Initially, this drop-in replacement part was an extremely tight fit. So much so I couldn’t install it. After applying a little bit of very fine 220 grit sandpaper to my Trigger Pivot Pin, and the inside of the GGI Adjustable Straight Trigger pivot pin hole, and liberal use of gun oil and elbow grease, I got the new trigger installed in my P226 MK25 (mine was manufactured in 2015 and has the DAK frame).
After a little trial and error, it’s now fully adjusted to my liking, too. Before and after photo attached.
Thus far all I’ve done is a lot of snap-cap dry-firing. I much prefer this new GGI 2-Way AST to my original OEM stock factory curved (“hooked”) trigger, as well as to my SS P226 Short Reach curved (“hooked”) trigger. The new trigger is more comfortable, provides me with a cleaner, surer trigger break right at 90 degrees, and a shorter overall DA trigger pull. The reset is really nice and short, too – I have the SRT upgraded trigger kit, previously installed.
It’s high time to head out to the range and shoot some steel.
Good things! 👍
Thank you for posting a product review! Please do call in to our customer service team when you have a few moments so you can tell them a bit more about your experience. They may have a few questions for you and they will want to ensure the the trigger for your MK25 meets your standards and ours.
Installed on my p226 mk25 and I’m sooo impressed. The trigger feel and performance is a vast improvement over the factory curved trigger. The dual adjustment eliminates any over travel. It was very easy to install.
So I put the adjustable flat trigger in an older SIG P229 chambered in .40 S&W. It had never been the favorite pistol, but its size and power made it useful for mountain treks, and it was good comfort during one encounter with a couple of mountain lions. Now I have a new fondness for the P229. For a relatively minor part swap, it makes the pistol much easier to shoot accurately and consistently. There is just something about a flat trigger that makes it more intuitive to shoot well, at least for this shooter. I very much recommend it; though I am starting to wonder if these upgrades are habit-forming. Excellent product.
Much better than the narrow stock trigger, really good feel to it, makes me shoot better. Less slop and a pretty easy install.
Excellent quality. No wonder SIG sells their products on their website. Already put a few hundred rounds on the trigger with no issues. Everything I was looking for in a flat faced trigger. Also the adjustment capability makes for a crisp trigger pull every time. Definitely recommend.
This trigger and G10 grips are two of the best and most practical upgrades for the P series Sig pistols. This flat trigger will spoil you!
I ordered the straight trigger, it is very well made. Shipping was fast. The price is not terrible either for such a quality part. After installing I was actually shocked at the difference between the straight trigger and the stock curved. It’s impressive. It really helped my Sig P229 in 357 sig. along with the GrayGuns Sig P series Custom Strut System. It’s like a whole new pistol, very smooth no stacking. At this point I’ve only dry fired with snap caps. I will have to qualify with it in the very near future and will update my review after running it through a qualification course.
I will be adding these same parts to my Sig P220 soon.
I just purchased a new Sig P-229 Legion. The trigger action is great. However, I do not like curved triggers. I purchased this straight trigger from Grayguns. Grayguns shipped the trigger immediately, and I received it in a couple days. The workmanship on the trigger is outstanding. The trigger was easy to install, and fit perfect. The two adjustments on the trigger sure make a difference in the performance of the gun.
I was impressed with the quality of the trigger. I was also impressed with how fast Grayguns shipped the trigger. Outstanding job Grayguns.
The trigger fits well and functions great. I shoot and carry flat triggers for duty. The trigger is awesome and changes the look for the better in my opinion.
