I actually contacted Lasermax and asked if they had one to fit the M or S series. They replied promptly they did not make one for the M or S series. I then replied that I knew that, but the qeustion was do they manke one that FITS the M-series. I haven't heard from them on this. I am not averse to making mods to the sight and/or gun in order to make it work, especially if I can pass it along to the rest of you gents. S&M pics are coming soon. I just have to find a final finish with the right properties (durability, grip, etc.).
