Just bought the Umarex 586 and generally, I like it a lot. One problem though is that I have had to set the rear sight on max elevation and max windage to shoot to point of aim at around 10 metres. Out of the box, it was shooting way left and way low. This is quite disappointing as obviously I have no sight adjustment left. As the pistol comes with 3 fore sights, I was going to lower one of those to give me some elevation adjustment. I can't see from an external examination though why it shoots so far left.

I could use a red dot etc , but I really wanted to shoot this with open sights. I'm wondering separately whether the genuine S&W rear sight will fit so plastic could be replaced by metal. Don't know how accurate a copy the Umarex is though.
