Hey Love the gun but hate there is nil aftermarket for it. I have ameriglo I dots on all my other guns. I like to keep things the same. Anyone know of any place that offers or will make tritium night sights or straight 8s for this gun?

Unless somebody else chimes in, you are gonna have to find out the dovetail dimensions and go from there. Or have dovetails cut to fit, if they can.
Cool guns, they just lack in upgrade department

Tooltech Gunsight, Inc. may be able to help.  They can be a little expensive.

rear sight dovetail is the same as an M&P

I really liked the half dozen .45 SAR K2s I handled in the LGSs, .... but after searching pretty thoroughly to see if some outfit (like Trijicon) made night sights for these Turk guns, I couldn't find any and decided to pass   -  at least until the aftermarket catches up.

Possibly the .45 K2's sight dovetails are the same dimensions as on Tanfoglio's .45/10mm-size slides (?).   The Witnesses have some aftermarket support in the way of sight upgrades, such as from Dawson Precision and Henning's custom shop. You might check with those vendors.

Thank you all. each response helped in its own way. I HATE to have specialty guns BUT if I can just find sights im going to keep it. I will try toolcraft

Not sure if you just overlooked my post or what, but there are pics of the K2 with M&P rear sights on it on czfirearms.us forum

No I totally saw that. Thanks. I really am more concerned about the front sight. A hi viz front sight would solve all of my problems. Anything under speed and out to 30 feet im using front sight. Anything past that and Im using the notch and goove.

I have a Hi Viz front sight for a CZ75 I'm going to modify to fit my SAR K2.  
You just have to remove the existing K2 sight and file the dove tail on the CZ sight to match K2 profile. Press fit it in and add a drop of LocTite.
