AFTER ENSURING THAT THE GUN IS UNLOADED, check to make sure that it is unloaded, and then when you are SURE the gun is unloaded, use that laser for dry-fire practice to watch what you're doing with the trigger pull.
The dry-fire will help you do several things: it'll smooth out some of the action parts; you'll get much more used to the feel of the trigger; and you'll be able to SEE what is happening as you squeeze the trigger through the shot.
Ya I'm an idiot...I am embarrassed to admit that I didn't even think of trying it with the sights. I will try it Thursday. I had the stand at about 15' and was low then, so I moved it back farther. I will say that twice the slide stop caught the slide preventing it from chambering a round.
