Could this be made to fit the Glock 21 (.45 ACP) I am fine with needing longer screws or minor adjustments with a Dremel.

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!)

Yes it will. I currently have it on my glock 21.it has multiple polymer inserts that will virtually fit about any rail.

Yes, I believe it will fit with no problem. I have a full size 1911, have not tried but easily holds a Glock 21.

This is not a universal fit part. Pearce does make an extension for the Glock 42 but in the Amazon listing you have to specify which model you want it for.

I don't see why it would not fit. But I am no expert when it comes to the different generations of Glocks. The base plate may make your magazine sit lower and not fit right in your pistol. Try contacting the business if you can, they may be able to answer your question better. I would hate to give you any bad info.

It fit glock 19 Mags a little loose, (I'm used to a nice, secure, kydex retention) so you should be fine.

Mako lists as being able to fit Glock 19 as oneof the models it is usable with. Mine is mounted on a 21c with a red dot on top and laser/light underneath.

I bought mine specifically for a Glock, not sure if the dovetail is a standardized size. Might look at the sales info to see which firearms are listed for fit?

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.

...I live in Alaska, so I think it will be quite a while before we see the G42 up here any time soon. This is the smallest pistol Glock has made, so you might go to the Glock site or the LaserLyte site and inquire as to if it will fit... Sorry I can't help you much...Mark

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

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.

I don't know why it wouldn't fit the front does match up to the trigger guard on the mosin but could be filed down if needed . It's a decent grip and it is a nice addition . The screw will work that's for sure . So I guess it's more like can you do a little modification if it doesn't ?

If i remember the 21 is a 45 acp? If your slide has a mount I would say go for it. It's actually a pretty damn good sight for the cost. I have it on my MP5 9mm and it has worked great so far.

I cannot specifically speak to the GLock 17, but I use a single stack 1911 (45 acp). So if you are using a glock 45, should work. Anything smaller, then you would just have to tighten down the "pinch" screw.

Its iffy. You can remove a few stitches to make it bigger. Itll even hold my hipoint so im sure a glock would 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.
