Don't mix! The safety on the right side of the gun is in the way. Since I got mine cheap on fleabay I did some very judicious whittling to make it fit but I can flip the safety off but not on with my left thumb. I looked on their website and only under fitting tips does it say they are not compatible. The box does say that but it was a little late by the time it showed up in the mail. They need a big disclaimer on the website. Laser works great but it was annoying to say the least. I also could not access the elevation screw while the grip was on the gun but it as easy to pop off and on.
