my sd9ve shot to the left wildly.
we, meaning wife and I, were able to help it out by wrapping our hands around the grip to the point out webs were on the left of the grip and making it hard to reach the trigger.
we were new to guns, but this was our fourth handgun, and accuracy was not a problem with any of them. Our previous two guns were a Sccy which, although undeniably extremely accurate little barrel, was a stoppage/breakage nightmare with a DAO that wore my wife's hand out quick; then off to the Ruger 9e which was a decent handgun and we experienced little issue, light with a decent trigger and we accustomed to it good(at least I did, was still frustrating with my wife),but it was very short-lived(4 months tops) before I ended up selling it off in a trade for an SKS during the height of the "scare".
Still knowing little of handguns, I saw the OTD price of the sd9e of exactly 300$ and the name recognition alone sold me one it. I am not going to knock the pistol, it bent bang for every 15 rounds out of each 16 round magazine(two mags), it apparently had shipped out with a lot of mags that had the follower to steep as to it put the bullet in the chamber at 90 degrees on every last round 99% of the time, the round would get crushed, pointing nose up, between the slide and barrel. I knew this would likely be an easy fix so it didn't mean much ATM, but the sighting issue was a problem.
I understood how to punch the rear one-way or the other, but just didn't LOVE the gun overall and wife despised the ergos and the "clunkiness", so I just tried to make do for a few months. Ten yards the vertical was always pretty "on" with 115gr but horizontally ti was just plain waayyy tooo left. so I can't immediately jump to the shooter and say it's
your fault, I have seen it first hand.
it's a pretty amazing misalignment to have a shift of 12+ inches at a 10 yard mark. I cannot say what the root of the problem was, but it's there, and if you and I have seen, surely a few folks at S&W have as well, I would check with them first(demand ACTION, then demand SPARE MAGS

) my trigger was pretty bad, but this was like 4-5 years ago, and I see they have switched it up a little.
I liked the look of the sights, they easily gained attention of eyeballs, even in the sun. sorry for your trouble, and hope my post wasn't just a pointless rant, just trying to let you know that others have experienced a similar issue with horizontal alignment, although my case nowhere near as remarkable.
I don't think if validates giving up on th gun f your other-wise are content with the pistol, Smith/Wesson should gladly accept it and run a ransom for you to clear up the adjustment or isolate an actual mechanical ssue, this wil at least allow you to figure out how bad a shot you are, or if your a sweet shooter that cant yield gains with this specific choice.
In the end, I went sa/da and holy cow is it better on the greener side of the fence, but if I went back the Ruger (we would have probably stuck for an HD'er and the Smith should got skipped. that said, if your hands are big, and fingers strong....the sd isn't a bad weapon and really it's a good deal if works correctly. it holds it's low-value well being a name like that, I sold mine for 280$ with one mag(lost other) and used, versus the 20$ more I paid at the store.
