Will it fit on a Glock 21?

Yes, it could be mounted on any rail, I believe. But it sure wouldn't go in any holster. The switch is on the back, it rotates, but it couldn't be absolutely tight against the trigger guard. I am not familiar with the Glock 21.

Use it on my glock 22 now which is the same frame size as the 21. I also have the G21 and the rails are the same size. So....yes.

Yes. There are rail keys that come with the light. Pick and install the glock one. The Glock rail key may actually come on it from the factory.

It should fit, from what I can gather it is the same size as the 21. It only has compensator cuts on top of the barrel with no added length.

No, unfortunately I do not think that it will. The Glock 42 has a smaller frame than the Glock 19 and consequently, it won't fit

I believe so. As long as you have rails with a gap to lock in place. The piece is adjustable for slim and wider handguns. If I were you I would compare the specs between your firearm and the glock model 21 (.45 cal) or to glock 22 (.40 cal). I have both of those and the piece fits perfectly

Yup it sure will! Fits great on my 29, 30s, 19g4, 34g4, and 21g4. I love it so much I put it on all my Glock's. Be aware that it does protrude about an eighth inch out to the side. I did have to modify a few of my holsters to accommodate this. Worth it though.

I'm sorry, I'm not sure. I have a Glock 23 and it fit perfectly. I was careful in installing it and did not experience any tearing as a few other reviewers mentioned.

I'm not 100% sure. If you have a rail in front of the trigger guard it should fit. It fits PERFECT on the G19.Good luck!

Not sure if it will fit yours, but it only clamps from one end, unevenly. Many have damaged their rails with this mount, including my glock.

It will fit all mid frame glocks, 19 23 32 an so on. Im unsure about a 25 best bet go to lone wolfs website

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

In reading the rest of the reviews I would say yes. It fit my glock 27 perfect. http://www.amazon.com/gp/aw/cr/B000KOUDQC/ref=mw_dp_cr?vs=1

I don't think so it won't fit a full size glock 21 so I'd try the one that fits the glock 21 cause that one is the full size 45acp glock! Hope this helps

It should because it comes with different fittings for multiple firearms. I have a glock 21 gen 3 and plan on buying one for it. I currently have this on a kimber 1911

All the springs will fit and work with the glock 21. That being said, you may have to file down the connector that comes with the kit.

Yes, it fits almost every glock model. I say almost because there might be an obscure model it doesn't. You can install in your gun in 3 to 5 min.

I use it on a Glock 21 ( full size .45 ) and although it fits, it's not snug against trigger guard. I would recommend this only for a nightstand gun. I don't believe the quality is suited for EDC or range use. I slide mine on at bedtime and remove when I leave the house. In that aspect it's well worth the money.

Negative. It has a different trigger guard shape. The light guard attaches in an odd way that will only go on a glock
