So I purchased my first Glock a few months back. G30SF...after some problems that have been worked out I love the gun. Just qualified for my concealed carry permit the 1st of the month and can't wait to get it back. This will be my every day gun. Now I'm getting married the end of August and she and I have been talking about gifts for each other. I want a gun. As much as I'd love another rifle that just isn't in the budget that we set for each other so it looks like it's time to get another Glock. I have started buying 9mm ammo already even though I don't own a 9mm. What I am really looking for on here after all my talking is advice on which 9mm to get and should it be a Gen3 or Gen4? Any input would be appreciated.
