I just myself a sweet 35 I was going to use in IDPA. While doing some practice, my slide slams shut when I slam my mag. I called glock today, they told me it was mormal? Normal really, none of my [email protected]'s do that. I am going to send it into the factory to make sure everything is cool, And this thing is shooting all over the place, Im not sure if something is moving around or what. I am going to have them go through it and put some night sights or steel sights on it. If this is a regular thing for the slide to close on its own, I will be putting it up for sale.
