This will also be short, subtle and to the point. With all the previous threads I was very paranoid about removing my sights; I used a rubber mallet with a brass punch, but also a rubber pad and had no problems, the warren sights slid right in for easy installation and alignment for windage. I fired around 700 rounds with different levels of light, from fast tactical draw to a slow weaver stance. Overall I would also have to pass making a purchase, if I am speed shooting I’d use my current sites the way the Warren sites are intended; just aim and click. For me I just like my Tritium night sights. That’s my opinion, but I would also like to thank Jester for the opportunity to try products this is a great testing program, thanks.
