I am new to the site, and I have a new glock 19 Gen 3 that I have run 400 - 500 rounds through without the first hitch. I also found it to be very accurate. I had some difficulty manipulating the Slide Lock and the Magazine release, and this was easily fixed in my case with the addition of an extended Slide Lock and extended magazine release. I was so pleased with the pistol that I thought the only other possible thing that may make it better is night sights. I decided on the XS 24/7 Big Dot Night Sight. My accuracy has gone all to h^^ and I am all over the place. Can't seem to get an accurate sight picture for most shots. Just wondering if anyone else has installed these sights and might have a suggestion on how to improve.
