I have a TP9SFx with a Vortex Venom red dot as well. I too think they have great triggers for an inexpensive firearm. Well built, come with a few RDS plates, a couple different backstraps. No issues for me.
My youngest just turned 21 and bought his first hand gun. A Canik TP9 Elite SC in Bronze was his choice. It's a good shooter so far and hasn't had a failure in about 400 rounds. This model, the rear iron sights stay on when the optic plate is removed. On my SFx, the rear sight comes off with the plate.
I wouldn't say the Elite SC has suppressor height sights, but they seem to stand taller than most iron sights. I'm thinking for the RDS co-witness.
