Will this fit on a Glock 21?

yes it will, all glocks have standard rail size , as long if its 2 gen and up

Yes. Fits the Glock 17 and 22 they use the same rail system. Sharp and short, I am sure you could do some damage someone if they tried to get your gun from you.

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!

I do not believe it will fit a Glock 23. It fits Glock models 20,21,30,36,37,38,39 so unfortunately I don't think it will fit the 23.

I had a generation 2 glock 21 and it didn't fit on mine.....so I doubt it will fit.....my trigger guard was too fat so it wouldn't sit right

It will fit all Glocks with rails. I use it on my Glock 21 Gen 4 and it fits perfectly. I also have an M&P; 9 full size. The light will not lock onto the rails. I believe it is because the trigger guard is shaped differently. This light was designed by Glock for Glock and unfortunately my M&P; would not accommodate it.

Yes it will fit, but it will be bulky. The glock may not feel secure enough for you !

Due to the Glock 21 having a larger frame this product will not fit properly.

I don't know, I have them on a Glock 21. I know the front sight will fit but i am not sure about the rear sight.

I bought this for glock 21-SF mags. I do not know if mags for other guns will fit.

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 don't have a Glock, therefore I dont know. It does not fit on my S&W; M&P.;

It will work with the factory rear sights. I am not sure that it will fit the Glock 20 or 21.

It will fit on anything with picatinny rails and should fit well on your glock

I have a glock 21 sf with a surefire x300 and it did not fit. Maybe with a smaller frame weapon it might but I couldn't tell you.

It should fit since the product list the glock 36 along with the glock 21 and 30 which the plate fits fine

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.
