Made in usa - LaserMax Guide Rod Green Laser Sights for Sig Sauer P226

I actually bought this Lasermax Guide Rod Green Laser Sight for an old "Made in W. Germany" SIG P226, and was amazed that it would not fit. The guide rod for this sight would not fit through the hole in the slide in my old P226 bcause the diamater of the laser guide rod was too large. I also have a SIG P226 MK-25, Made in USA which has the same size guide rod as the Lasermax Guide Rod, and this laser sight fits that pistol perfectly. On my "Made in USA" P226, this laser sight is right on target at 15 yards. It makes getting on target easier and faster. The green laser is very bright and easy to see in both day time and also at night.
