I am interested in the Glock 19 Gen 4, w the double recoil spring and adjustable grip. I would like to know if the rail mounted laser on my Gen 3 Glock will fit securely on the Gen 4. Does anyone here have access to both the Gen 4 G19 and a caliper? If so, I would MUCH appreciate if you could post the dimensions of the bottom rail interface surface, specifically the width and depth of the cross slot etched into the bottom of the frame, the distance from the end of the frame to the beginning of the cross slot and the overall length of the accessory rail. Thanks in advance for any guidance you can give a fellow Glock enthusias...
