One size doesn't fit all as advertised. - Crimson Trace Master Series Lasergrip w/ Green Laser for 1911

I have 3 1911's all with laser grips and they are great. I bought a LG-902G for my Springfield Ronin 3 inch barrel. One size doesn't fit all as stated. First of all the grips covers the mag release lever on the right side of the frame. I had to use a rat-tail file to cut enough clearance in the grip in order to get the mag to drop out. The second thing is the counterbores in the grips are too big to hold the grips secure. The grips move around under recoil. You can't hold zero because the grips move. The laser is made too tall and rubs the bottom of the slide. I wish that I didn't buy them.
On a positive note.......... the laser turns on.
