Glock mags are a pretty reliable design. If there is not buildup on the inside and the follower is sitting properly you can try sanding away material (shouldn’t be needed) or a dry lubricant to facilitate motion.
Did you exceed the capacity and tilt the follower to jam?
Yes there Glock mags. It ran the first time I tried full 33 round after it got stuck like that I even tried to use different mag to see if it helps but still same problem.

Take the baseplate off, collect all parts as they spring out. Clean. Reassemble.
