Outside their customer service apparently - but that's pretty much par for the course for these companies. Last time I held one I wasn't a fan of the trigger - have you done any good upgrades there? Also sounds like I'll need a gun smith to change the sights.
you don't need a gunsmith to change sights. The front sight is a Glock replacement and the rear is fine unless you REALLY need to change it and I believe an M&P rear sight option can be fitted with a little filing.
Yes, I did some stuff to improve the trigger.
1. the striker blocker in the slide is oversprung from the factory, Galloway used to offer a lighter replacement but after talking to them, they are discontinuing SAR9 stuff. Not sure why.
2. The trigger absolutely benefits from a $.25 Glock style trigger job if you will. Being it has the "chassis" around the trigger group, the trigger bar runs against metal rather than polymer in a Glock. The inside casting of my chassis was rough and the trigger bar was scratching a line into it. I did a 1000,1500,2000,2500 sanding and buffed with a dremel with jeweler's rouge to smooth it up like glass. Also, the tail of the cruciform on mine was rough causing drag on the striker face. I sanded and polished that the same way.
3. The OEM connector is coated in some black finish. It isn't smooth. All I did there was some jewelers rouge on the dremel to buff it down to bare shiny metal and coated that articulating surface in grease.
I did the complete trigger job including detail strip and reassembly in under 45 mins. Remember on the Glock style trigger, the trigger spring ASSISTS the pull, not retricts it. the SAR model trigger spring is stronger than an OEM Glock one. leave it alone.
Also, my trigger safety sat proud of the trigger face on my gun and hurt my finger pad. I pulled it shut and held it in place tying it to the trigger guard with a bread bag tie and sanded off the excess material with 220 grit wrapped around a marker. I finish sanded with 400 grit. The trigger feel is MUCH improved.
Now all it needs is some more rounds ran through it.
