I just got a new Highpoint 995 9mm. I love it. BUT there are some weird things about it that I'm not sure are normal. #1, when you press the mag release the gun has to be straight up and down for it to come out, sometimes I have to shake the gun to get it out. I'm used to my handguns and the AR that the mag springs out almost. So I don't know if this is normal or if there is something wrong. The other thing is it hurts to shoot it. There is obviously no recoil, but the vibration is so strong that it left a bruise on my shoulder and it feels like its rattling my teeth when my face is up against it. The one I shot in the past I don't specifically remember that and I feel like that would be something I would remember. Any insight?
