I bought Warren Tactical sights tritium front and plain rear sights for my Glock 22 duty gun. I had them installed by Neves, and they dented the rear sight pretty bad with the sight pusher. I even told them we might need to file before install. Well I purchased a single Warren Tactical 1 dot night sight to replace my plain rear sight. I once again took it to Neves during Glock Days to have a certified Glock Armorer install the sight and do a detail clean. Once again I stated that the sight are a tight fit and might need filing. Well the sight was installed and once again it has a dent on the side of the sight. So long story short, I will be going to pick up my Gen4 23 here in the next few days. I already have a set of Warren 2 dots to install, but I am hoping there is someone who can help me install the sights without denting it this time??
