I bought a S & W SD9VE
Nice piece for the price. Like Tex said, the Apex trigger is sweet and changes the geometry so the take-up is much shorter and reset is nice. Not a big deal to replace it if your comfortable with that kinda thing. Love mine (for what I have in it) Its my couch gun with a stack of mags. Mags go on sale regular for 10 bucks too.APEX makes a kit to improve the trigger. YouTube has the instructions for the swap and it looks fairly easy.
If you like the "heavy" trigger then you only change the trigger, no springs. The weight on mine didnt change any for just a trigger swap.
