I plan to buy a NIB M&P Shield "no thumb safety" 9x19mm this fall.
I will add Trijicon HD 3 dot sights too. I'm impressed with the steel orange-green sights. Trijicon is a shooting sports/military industry leader.
I'm thinking of having a Cerakote treatment too. Maybe SOCOM blue with the tactical grey color(lower-frame). It will void the S&W warranty but that's okay.
I like the X-S big dot sights too but my first choice is the HDs.
Note; many gunners & engineers say green is the best color for night sights, but I like the orange/green style.
