I've heard good things about them, though some people are hesitant because of the whole "Turkey funding terrorism" thing.. I don't know enough myself to know for certain.
I've got the TP9SF Elite which is the Glock 19 sized version. Love the gun. Have had no issues at all with it, and it shoots just as well as my VP9 for me anyway. Maybe even better if you consider how much more I shoot the VP9 compared to the Canik. For what I paid, it was a steal. I did have some trouble getting 10 rounders, but Buds finally got it right on the third try. The X version looks badass. Let us know how she handles.
