Thank youI work on Glock triggers regularly but have no interest in trying to disassemble a SAR9. I think you will find it a little more complicated than a Glock but everything is more complicated than a Glock. As long as you just polish mating surfaces you should be ok but understand the difference between grinding and polishing. Good luck
In my case for a carry pistol I was happy with just the polish and the results were noticeable. I would be weary of every joe bob stoning their trigger. I would say that would be a recipe for a bunch of NDs. Sure people that are careful and have an understanding of what is going on is fine but that isn't the majority.
Not knocking anyone or any brands, but a lot of the reason I went Glock when I moved to striker fired guns is popularity and thus information.
Tons of YouTube's, forum posts, sites, etc. dedicated to this simple procedure to smooth up the factory trigger.
Kinda like buying the most sold Ford or Chevy. Lots and lots of information, accessories and aftermarket readily available.

No trail blazing, guessing or trial and error necessary.
A couple of passes with a fine Arkansas stone on the ramp of the vertical extension ( the part of the trigger bar that contacts the striker block ). Then a drop of oil between the birds beak and the connector per Glocks lube instructions that is all you need.
I think the key is just to polish by hand. I did my G19 with a qtip and mother's metal polish. I think people get into trouble when they try to use a dremel. You aren't trying to change any geometry just make the surfaces smooth. Look up 25 cent trigger job on youtube for a glock tutorial.
If I wasn't so invested in the M&P line, I would have Glocks. I don't own any but I usually recommend them when people ask me about what to buy.
I am a Glock guy as I got invested with piles of mags and accessories 10-15 years ago. If I had to start over, I would be torn between a Gen 5 Glock 19, P320 Compact, or M&P 2.0 Compact. They are all excellent guns and all will serve you well.
If I understand you right, this is what I do on my Smiths. I work the trigger bar wherever it makes contact with steel and for Smith's I put the Apex USB in. That's all I do. I even run the factory trigger.
On another note, I just pulled the slide on mine. I need to clean it!
The only thing that polishing does is make it shiny. Yes you can make a rough surface shine. Rough surfaces that contact each other need smoothing to the point that the high spots slide over the low spots on the opposing part with out dipping into the low spots. The low spots hold oil.
I posted this in another thread, but felt it fits here.....
