Welcome from Cajun Country.
I already own the SW9VE & SW40VE. I just recently bought my SD9VE from my son. He only put about 100 rounds through it and decided he wanted an M&P instead.
To my SD9VE I added a factory S&W M&P rear sight, a Galloway 20# Glock G19 stainless steel guide rod, and a Galloway wide take down bar.
Of all of the aftermarket parts, IMO, that was the best investment is the wide take down bar. Removing the slide is 1K times faster than with the factory bar. It might seem trivial to others, but, I find removing the slide quickly and so much easier now.
The G19 SS guide rod is $12 cheaper than the Galloway S&W ss guide rod. And, it fits perfect. It sure helps keep muzzle rise down.
The factory SD9VE rear sight is a joke. It's plastic and there are no indentations to paint the dots. The factory M&P rear sight is metal and has indentations for the white painted dots. Brownell's sells them for $14 and change. DON'T FORGET THE SET SCREW
One last thing; this pistol will shoot ANY type/kind/make of 9mm ammo. It eats like a hog and is built like a tank!
