Question: Has anybody tried this on a CZ 75B?  How's the fit?
Document: tried it with multipal handguns and it didn't fit anything in my arsenal, it needs a list of compatible firearms.somthing like this you can't buy for a gun, you buy a gun for it.
Purchased along with Bushnell First Strike Red Dot Sight for a CZ USA P07 Duty 9mm. The mount fit on my gun and the gun operated briefly with it on. But, 2 times in a row, the mount fell off after only 3 shots fired. Both times I had the mount tightened as much as i could to the point where it was starting to dig into the polymer frame. The design flaw is that there is only one screw that holds it in place and it doesn't even run through the slots of the rail.
I wouldn't go as far to say that it &#34;FITS MOST&#34; pistols.. I've tried it on many and it seems to fit a Glock ok.... I tried it on Sig, Taurus, Bersa, magnum research and no good. good luck on this one guys.
I can't think of a pro for this item but there are lot's of cons. First, it's to expensive (50 bucks) for something that isn't a custom fit. I bought this because in the picture, it looks like it fits a SIG SAUER. I tried it on two of mine (2022 and 225) and it scratched the barrels on both. Once I got it on, it looks completely ridiculous and it doesn't point straight ahead because it's two small for these guns (points down ever so slightly).
I should never have tried this product on my railed 1911. I thought it would be nice to be able to add an optic over the iron sights. When I got it, there was no screw. Had to get it at my local hardware store for about $0.50. It scratched up the rail every time I tried to fit it on. I ended up putting 3 scratches on the top of the slide (from fumbling with the tight fit over the rail), which now drop the value of my gun.
The machining and quality of this rail is excellent. Tried it on three of different pistols to see how it would fit. First pistol, a glock 30. The width of the larger frame glock seems to be an issue. The top outer edges of the glock 30 slide DO rub on the inside top edges of the rail mouint slightly. Removing a little material from the inside of the rail mount would definately remedy this problem. Plenty of height clearance on the glock 30, but not enough to field strip it without removing the rail mount.
Very disappointed. Spent around $60 bucks and it wont fit my brand new Sig P250. Not only that but it marred and ruined the nitron finish on the slide when I tried to remove it after it wedged itself against the slide. Attempting to file the inside of the mount down so it is able to clear the top of the slide but it appears that my efforts will have been useless. Please don't use the term "universal" if the product fails to fit the most popular models. I'm sure the mount would have looked awesome on my Sig but now that the slide finish is ruined and the polymer mount is all torn up my sig looks like junk.
I tried this for my brand new Browning 1911-22 A1 Black Label Laminate and it does not work on that either. It fits the rail and clears the slide by a mile but it completely blocks the ejection port.As others have said, I was hoping this would fit my gun. I even tried it on my XDm 9mm 5.25 just to see how close is would be and if machining away material was a reasonable option......nope.The quality of the piece is good but &#34;Universal&#34; and &#34;Most&#34; are the last words that should be used in the description of this part.
This item didnt work out. Bought it as a gift for my brother. We discovered that the rails on the pistol MUST be original on the pistol and not an aftermarket addon or the mount wont slide over the gun slide. period. And a neighbor tried it and again..the barrel MUST be a minimum of 4.5 inches or it will cover the ejection port. Going to be posting the one I bought as a gift back here or on ebay...
It only squeezes. If you could machine another hole in the exact right spot so that the bolt would run through the slot i think it would work. Or if your gun has a steel frame i think you could tighten it down more and not have to worry about damaging the frame.Note:My gun's barrel is only 3.8&#34;. Some reviewers said that this mount covers the ejection port. i wonder if they even tried to cycle a round by hand to see exactly where the slide stops and the case is ejected.
Answer: yes
