Hi folks, I want to get Truglo TFX for both my 228 and 2022. Which sight fits? #8 #8 set or #6 #8 set?

The P228 standard sight set is 8/8. For the SP2022 it depends on chambering: 8/8 for 9mm and 357SIG, 6/8 for 40.

Thank you so much! They are both in 9mm...

Look on the sight for the # or measure them.
Sig can have anything on it from what I have seen.

Depending on the year it was made, the dovetail for the front sight on the SP2022 might not be the same as a P-series.

I had this come up at a shop when I was going to have them install Truglo sights while I was buying my SigPro back in 2012. They couldn't determine which sight was the right one (I ended up letting GGI install a Warren/Dawson combo). YMMV. Good luck!
