Doesn't fit a smith and Wesson or a sig sauer rail... so just saying  do your homework on the dementions of your fire arm
its made to fit my beretta storm, but it don't, its loose on the rail does not fit at all and the gun has a picatinny rail on it  so it should fit but dont
this does not fit standard weaver rail. it could be made to if you are or know a machinist. it may fit &#34;some&#34; accessory rails on polymer framed pistols, i cant say for sure. i will say that they were fast about returning my money and the shipping was on time.
I just got this yes it was a little loose but you can file down a little bit to get it to fit perfectly I have it mounted on my Taurus pt 1911 ar with no problems the other reviews complaining about it sitting too high it has to so it doesn't mess with your fixed sights people don't know what they are talking about its a great product
I have a Sig SP2022 and it did not fit snug with the rail under the barrel at all. It was loose and would slide forward and back just by pointing the barrel up and down. Had to modify it with epoxy and plastic wrap to make the adapter a little smaller where it attaches to the pistol. Fits tight on other spare rail parts that I have just not the one that is on the pistol itself.
I found it needed several modifications in order for it to fit properly. The included pins were too long to let the clamp portion fully close. They needed to be shortened. Also, the clamping part needed filing to get a proper fit. If you are handy and don't mind a little work, it is ok for the price. Once adjusted, it is very solid.
This item does not properly fit the Springfield Armory XD(M) .45 4.25&#34; barrel or the 3.8&#34; compact. The item is durable and the installation is simple. However the side of it does not allow enough clearance so that the takedown lever is still able to be accessed. You may fit this to the aforementioned pistols however, no matter how you attempt to fit it on the rail, it will always block the takedown lever.
I don't write reviews unless an item is really bad or really good... this one is really GREAT! Negative reviews for this product are results of operator error. As with any such items, a drop of locktite on the fastening screws is all that is required for solid trouble free performance. I've purchased 5 top rail mounts for my Sig 2022 and NONE fit properly. They just couldn't clear the slide action or bends and flexes to the point of uselessness. This one clears with room to spare.
With the extra rail on top and side I can configure my weapon in different ways..feels light but made strong ..for the price u can't go wrong..
