In the first hour of shooting with my Shield 9mm (with factory night sights) on 115gr winchester white box, i shot at 25 feet and was all over the place the first few mags (this was the first outting with my new gun). After that, the groupings were to the left (i think on my part) but fairly tight for 25 yards. The funny thing is, after i put it out to 50 feet my groupings got a bit better (maybe because i was taking my time a bit more). Needless to say, it's a good gun for self defense. Just don't expect target gun quality. I also got an H&K VP9 and while i got a bit better grouping with that, it also shot the left for me. I'm happy with mine and coming from a background in pellet rifle shooting and this being one of my first two guns i've aquired in the last two months, i'd say it did well for me.
