That’s kind of the debate I’m constantly in. If I ever return to striker fired, it will be either Glock or M&P.
The M&P has a lot of things I like, and does have an ok TS option, but not a great one. Not for me anyway.
The Glock has endless support, NY triggers for those like me and the SCD. However, I would rather have a good TS and I have no idea if SCDs will be produced again.
