1911 Picatinny Rail Adapter Mount, 20mm Under Rail Laser Flashlight Mount for Colt 1911 and Clones，with Four Screws, Four Nuts, and a Hexagon Wrench

Does not fit on Springfield 1911 at all

Went this morning to my local gun range to put my pistol through the paces. The item fit was good but when I affixed my Olight Balder Pro it fit really well. Then everything went down the tubes. My pistol is a straight, out-of-box, 1911A1 Gov't Model made by Tisas. The ammunition I use is 230 grain FMJ manufactured by Sellier&Bellot. I made my proper adjustments to insure the Olight's laser was aligned to my pistol's bore axis with a boresight laser. After the first round out I notice a significant drop with the Olight system. I checked and cleared my pistol and saw that the entire mount was drooping down at/around 20-25 degrees. I thought that I needed to just tighten the screws that hold the rail mount to the trigger guard. I did such and resumed my exercise. Nope. Did not fix the drooping issue. So I took the Olight off and just decided to go with my iron sights. No fast shooting, no hot loads, no +P ammunition, just plain old 230grain "ball". On the third round I felt something hit my safety glasses. I set my pistol down, notified the range safety officer and found out that the whole item had literally shattered. The only piece that was found was part of the pivot attachment screw. The long thin screw shown in the item's photos. Please understand, I was really hoping that this item was worth owning and I don't pay much attention to the reviews because people will say anything about anything,so I took the risk and purchased it. In just my personal opinion, if you want this for Mil-Sim, Airsoft or a BB/pellet pistol then it would be a really nice add-on. But, in my personal opinion based on my personal experience, this item is not meant for an actual firearm, nor should it be considered for use on one. This is my personal review based on my personal experience. Nothing more, nothing less.

These are tricky I have the rock Island 45acp tac single stack and the rail didn't fit lush up against the barrel what was stopping it was the plastic inside the trigger made it tilt so I got out my Dremel tool and sanded it down and accidentally did too much so now it's not snug so I put a little strip of gorilla tape and it fits now just jankie looking so needless to say I think they probably fit some kinda 1911 just not mine

It fit super nicely

Not only does this rail not fit standard 1911 frames, but it's also made from cheap "Army Men" grade plastic that will absolutely melt if you shoot while this is attached. Mind you, you would need to Dremel this piece to even somewhat fit in the first place. This is a cheap, shameless scam. Do not buy this.

When fitted, does not line up well, there is wiggle. Also cuts down the size of the 1911's already small trigger guard. Works fine for a flashlight but securing a laser to this is not an option. Cheap and adequate option to serviceably get a light on a 1911.

fits perfectly on 2 of the 3 1911's i installed on, minor trimming on the 3rd to make it fit

Definitely not what i expected quality is very poor even if i plan to use on airsoft model it will not properly fit but it arrives very quickly and it looks the part just not functional
