Glock 19 Gen 3 Magazines

[larryis1]

Will a magazine for a Glock 19 Gen4 fit in a Glock 19 Gen3? Or do I need to make sure I only buy magazines that are exclusively identified for a Gen3 pistol?

Gen 4 mags will work for both generations. Generation 3 mags may not be compatible if you decide to switch the mag release to the right side of the gun.

Thanks for the help.

What Arias said. I use the ambi mags in my Gen 3 all the time.
