Will this fit a Glock 21 pistol ?

No, this is made for rifles. It needs 1 or 2 inches of rail to fit as well as being to wide for the front of a pistol frame.

"Product DetailsProduct Dimensions: 3.8 x 1.5 x 4.5 inches ; 1 pounds"I think your answer was the first line of the product description.

No. This kind of laser sight is best used on a long gun. It is too large to use on a handgun.

Not at all this item is actually somewhat large it's meant more for ar-15's and at-10's

The correct model holster for Glock 21 will hold the Gen 4. Mine is for Glock 23 and both generations I have fit properly

It fits Sig P226 with 4.4" Barrel. I believe Glock 21 has 4.6" barrel, so it should not have any problem fitting Glock.

Yes, it will fit any of the glocks. it is well suited to larger framed glocks (17/22/34/35). This is a great set of sights for a great price.

no it will not....screws are too short to fit across any glock...I tried it on my 26(which is what I bought it for),19 and G4 17....a gunsmith may have screws with the same threads that are longer so if you buy this know you will have to find longer screws elsewhere

No, it will only fit 9mm and 40 S&W...; (In my previous answer I'd said yes.. Because I misread the Glock model. sorry for the inconvenience!)

I think that it will fit, but you may have to trim it at the bottom. I have one my Glock 22, and I have roughly 1/2" of the grip extending past the hogue grip at the back and about 1/4" at the front.

I seriously doubt it will fit. I put a small laser on my Glock 17 and it would not fit.

it fit my Glock 21 double stack. my advice is to compare your magazine, with a double stack. if your magazine is much thinner I would say no probably not.

Well, I'm sure Galco makes them for a Glock 21, but the one I bought is for a model 1911 Colt.

Yes, I bought it for my Glock 27 and they are the same size. It will fit perfectly

I don't know about glocks. Check their website, they should have a matrix showing what fits what.

I am not familiar with the size of that weapon. It fits my Glock 22 perfectly.

Yes it will, I have the G 21, same size exactly as yours. Fits perfectly, nice and tight, I have also used it on the quad rail on my AR.

I have no idea. I'd suggest talking to a local gun dealer, or perhaps you can fine something on line that will tell you what it fits. Works well on my Glock 19

Yes, it will. I have one on a Glock 21 Gen 4. It fits just like the TLR-1 but it is high lumen (very bright). If it is important to have a holster, make sure you pick a holster that will fit the weapon with the flashlight attached, personal preference for law enforcement.
