Question: Will this fit a Colt 1991 Government Double Action .45 ACP?
Document: perfect fit for my Colt 1911. Be aware that this grip will not work with ambidextrous safety but works fine with single safety.
NIce fit, just like it was custom made for my Rock Island Govt Model 45. No lose spots or gaps, screw holes were a perfect line up with the screw holes in the 45. Easy to activate, just about any size hand could activate the light. It is almost spot on with the bore sighter that I slipped in the barrel to check the alignment of the sight.
My main hope is that the intimidation factor of the light may save some idiots life, if not it may save mine. I plan on buying another one of these for my other 45.
There is no way you can fit these grips onto this pistol without filing off a small amount of grip on the left side just below the slide. Once this is done the fit is perfect. I highly recommend them.
Bought this grip for my Ruger 22/45 and once you file the angle adjacent to the bolt release a little, it fits perfectly. I was reluctant at first to buy the Black grips thinking they might turn out to look like cheap plastic, but they do not. Once on the gun they look very sharp indeed. Understated, but sharp. I even managed to retain my Pearce Gun Grip inserts (PG1911-1), with a little trimming. I love the Rubber Finger Grooves.
I had to buy standard size 1911 bushings due to the increased thickness of the two, for those interested they fit the stock just fine. I cut off the top of the Pearce insert just below the magazine eject pin on the laser side, so the laser would sit flush against the stock The inserts are only 1mm thick so there's no problem there. I had to use the low profile bushing that came with the gun for that one screw (just below the laser).
With age and a little loss of vision, this aid has put me back on target! I wish I had laser sights on all my guns,
Very easy to install, works great, cost was very reasonable. Sighted it in initially at home using iron sights and the LASER, then refined it at the range. Very happy with  the purchase, great for home defense in the dark.
The product arrived from the 3rd-party vendor earlier than promised. Grips were easy to install, and the laser works exactly as described.The manufacturer claims the laser is pre-adjusted, but mine aimed low & to the left. Crimson Trace includes two hex wrenches, although only one is need to make adjustments. Adjusting was easy, and the red dot now appears right where it needs to be.A great product which I recommend to anyone wanting a laser aiming device.
The laser itself works as expected, just fine. This is not my first Crimson trace laser. What's neat about these lasers is the ability to practice and see exactly how much pull off center you have, If you can dry fire your gun, that is. As always, Crimson Trace makes a quality product. I'm well pleased with these Grips, so far, so good.
