Hello all! New here from Norcal! I am looking to get a G34 or G17 so I can get into the professional shooting match (After I polish up my shooting skills lol). I only have a G19 now so I would like to ask some advises from all your Glock Guru If I am planning on using this glock for competition, GSSF, USPSA etc, are there major benefits picking a G34 over a G17?Thanks!
