Hello, I'm new to the site, kinda, and I am getting ready to take possession of a brand new EXO Glock 23. I have a lot of questions to start with. First, I have a friend that has a 23, and neither of us shoot it very well at all. Horrible groups at 50 ft, plenty of flyers completely off the 12" target as well. I come from a Kimber compact 1911 platform, and he comes from a 9mm CZ-07 Duty platform. Are we just not used to it and just need to practice, or are we just that terrible? I can land rounds in three inch groups with my Kimber, even in bullseye league. Obviously, different kind of firearm, but I would figure something close to that would help. Any advice on shooting them? I have also seen many people say to polish the internals and drop in a ghost trigger? I have seen how to do it, looks pretty easy, but this will be my carry gun/self defense gun. I would really hate to do something that could get me in some trouble with a lawyer if, God forbid, I have to use it to protect myself or my family. Any advice on what to upgrade, if anything at all? I have standard sights on it, so night sights are a given. A little bling with NP3 pins and extended slide release look enticing as well. Any feedback/advice would be greatly appreciated! I'm looking forward to getting shooting with a glock finally!
