(I know others have done these same upgrades years before me... but I'm amazed at the results.)

Just got back from having someone else install 3 upgrades on my SD9VE (because I am tool-averse, mechanically incompetent idiot or I'd have done it myself).

The upgrades were the Apex Trigger kit, the Apex Tactical Spring kit and the slide release extender. While the last is okay, the first two literally changed the feel and operation of the pistol for me. The trigger has much less slop/slack and overrun and it pulls so much lighter and easier.

I did a quick operational check when I picked it up and then ducked into a nearby indoor range to fire off 50 rounds. Boy what a difference! I found it cured my "jerking" problem with trigger pull and I could control the reset much easier also.

Best money I have invested in the weapon thus far.

(Might be the last, though I am drooling about some fiber optic sights I saw on someone else's weapon...bright, bright bright in daylight!!! Unfortunately, money is not an endless resource for me.....)
