I shoot my new xd9 sub on the honey one day and crappy the next. I think the pistol is on but I am off. I do well with my Glock35 Super Redhwk. 44 my buddy's Sig and M&Ps .45 and. 40. Why such issues with this blocky little 9? I swear I have the top of the front sight level with the top of the rear and still miss. Should I ditch the gun?
