Burris FastFire Series Secure Reliable Durable Easy-to-Maintain Mounting System for Red Dot Shooting Sights

It is a very good and quality item.

As advertised, delivered on time.

The product itself is good quality and comes with plenty of hardware and a tool to get the job done. I had to return it becasue it will not work for the Springfield XDM-elite OSP. Burris indicates it fit the XD (which it probably does) but on the optics ready XDM-elite its placement interferes with the "load when up" bar. The proper plate for the optics ready XDM should have a notch cut in the front to avoid that interferance. I recommend ordering the plate directly from Springfield, the price with shipping is pretty much the same and they ship via Fed ex so it arrives very quickly.

This is a quality made piece, that fits very well, very snug, and aligns well. The FF3 mounts to it and it's solid as a rock. Very easy installation as well, it comes with extra screws too in case you lose one. Great product as far as quality and for what it's meant to do.I gave this 4 stars because 3.5 isn't an option.I bought this mount so I could mount the affordable FF3 to my S&W to try it out before sending the slide to have a slot machined out for regular mounting.I shot it today and it held up great and did it's job. However, the mounting block is so thick and so high that you cannot zero the FF3 properly. Point of impact is well below point of aim, about 4-5" at 25 yards, and about 2-3" at 10-15 yards, and that's with maxing out the elevation setting on the FF3.The mount should have been made with a downward angle, leaning low in the front, so that you can adjust the FF3 to at least zero at 25 yards.For the purpose it's intended, mounting to a dovetail so you don't have to machine your slide, it's great. I just wish they had accounted more for the height above bore and tilted it down a few degrees.Quality 5/5Fit 4/5Installation ease 5/5Design 2/5Price 3/5If you don't have a CORE series (the FF3 mounts to the number 5 plate) This mount should only be used for temporary mounting or if you simply don't/can't pay for the machining of the slide (about $200 every where I've checked)I'll be sending my slide away for machining but this mount helped me determine if I like a red dot on a pistol (never experienced one before) and I ended up loving it.-Marine Vet/Police Officer

Because my old eyes cannot focus on the front sight and the target together I caved in and decided to compromise my Colt Gold Cup by putting a Burris Fastfire III on it. I have 4 FF III's on wheel guns so I am used to the function and know the quality of Burris. This Mount promises to work on 1911 Adjustable/Novak sights pistols. It may work on some, but not on my Colt Gold Cup. It seems that Colt Gold Cup's have a range of rear sight configurations. My stainless, Series 80, 2012ish Cup has a Colt branded rear sight. The Colt pony icon is etched on the top plane of the sight and the Colt text logo is on the left side. The width of the dovetail is 9.26 mm and the depth is 2.5 mm. The dovetail is equal on both sides. However, on the slide the dovetail opening is wider on the left than the right: about 9.94 mm left and 8.66 on the right. The dovetail that comes in this package is 12.11 mm wide at the base on both ends and the angle of the sides is far greater -- I am guessing 60 degrees versus 45 degree for the Colt OEM. I called Burris and was greeted by a well spoken and knowledgeable support person. He told me this is a common problem and there are many different sight mounts even for the same model handgun. He is going to mail me three dovetails hoping that one will fit correctly. No charge. I will update this post with the result.

Only 4 stars for now as I have not actually take the part out to the range for test fire as of this writing. As the previous writer stated "dissatisfied with the fit of the dovetail mount. Was provided (2x) dovetail mounting options: 1 for the Cougar and 1 for the 92/98 mount." I too have a 92 and found that the 92/98 dovetail adapter was way to small. The "Cougar" one was a little better fit. I am not sure where the other writer's Beretta was made at, but perhaps the 92/98 adapter will fit the American built Beretta, and the Cougar one will fit the Italian made version. Either way, it seems as if there is an adapter available for your 92. Very well made part, fit and finish are excellent, contains two set of screws (2 long and 2 short), lock washers, and tool to install the screws. All you need to do is push out the sight that came with the pistol (be sure you are pushing it out right to left when viewing it from the back side) and push / tap in the adaptor, set the base on top of the slide and screw it down. I topped it off with a Burris Fast Fire III from the same seller. Will update this post under my review of the Burris Fast Fire 3 after I have gone to the range and tested everything out.

After way too much reading, I decided to grab the Burris mount and Reddit for my MK series Ruger.This mount is clever, the screws that go through the Burris Red dot drop through a hole in this mount and attach to a wedge that you place in the dovetail. (Clamping the assembly In place).Don’t worry, the bottom of the mount is curved to match the mk series receiver. It’s a very clean install.I’m very happy with the setup.
