I really love my 3913 but I don't carry it much because I'm not all that happy with the sights. I have Ameriglos on my M&P and it has a tall front sight with lots of light on either side so shooting it easy. The 3913 sights have a smaller front sight and rear notch. I know there are wide notch Novak rear sights but I also see Warren has a rear sight for 3rd Gen S&Ws and 10-8 has a rear sight for the SW1911 they say will work on the 3913. Has anyone tried these yet on their 3913/6906 yet?
