About the Glock 20

The Glock 20 is Glock's full size 10mm: a 4.61 inch barrel and a 15 round standard magazine. Short frame versions are listed as the G20SF. It is the same size as the Glock 21, so holsters are often listed for them together.

Magazines from the Glock 40 fit it too: they take the same magazine, and theirs are as long or longer. Shop 10mm ammo.

Glock G20 FAQ

Do you have the Glock 20 in stock?

Not right now. Our G20 listings stay on this page while they are out of stock, so you can see what we carry and check back.

What calibers does the Glock 20 come in?

Our G20 listings are chambered in 10mm.

Do you ship Glock 20 pistols to my house?

No. A firearm bought online ships to a licensed dealer (FFL) you pick at checkout, and you fill out the transfer paperwork there. Magazines and most parts ship to your door where your state allows.
