Kevin, yes Sir it is capable within a minute to change to the Glock Magwell Adapter to use Glock 17/19 Magazines no issue. Cheers and stay safe!

Yes, you can make a switch to use the Glock 17 & 19 magazines.

Kevin, yes sir, this will accept Glock 17/19 magazines. This ships with the Ruger magwell installed but very simple to switch to the Glock magwell, only takes a couple minutes. Hope this helps.
