Hi, I’m from European Union and my native language are not English so please excuse me some of my further mistakes. I have two Glocks (17 - 9x19mm and 35 - .40 S&W) and I’d like to buy a Warren or Heinie sights for one of them (maybe for G17). I’ve used Hexsites (some like ghost ring) and Ameriglo and I heard about XS big dot’s good performance too. One think is for sure, the best sights will not compensate poor shooters skills. Buying sights will not buying skills at all, but will help medium shooters to improve their performances. So I decided to replace Glock’s plastic sights with one bette. I’d like to find good balance between personal defense and practical shooting using. I’ve carried my guns alternatively for personal defense and some time for participating at the local IPSC events. As you may know, the vast majority of gun fights occur under the low light conditions. So, I think tritium in the front sight and one dot tritium for the rear sight will fit best for personal defense requirements. I’ve read that theses sights are good for practical shooting too. I heard that rear serrations of Heinie’s are distracting the eyes form looking to (not at) front sight or to the target and that WTS are very good for rapid target acquisition. I can’t decide myself which of them to chose: Waren Tactica Sights (with its special design) or a Sevigny Carry (with D. Sevigny’s champion reputation) or something else. What is the difference between them (not only as design)? Should I chose front sight 125 wide and 245 tall (shoot where you aim) or 215 tall (for 6 o clock aiming – center hiting for medium range). If some of you have experience with these sights please tell me your points of view. Thank you with anticipation.
