Could be, too, that mag springs are getting weak...

I say that because the force (from the ammo) needed to cycle the gun isn't that different from that needed to lock back the slide... but weak springs (either in the mag or in the slide lock mechanism) can conspire to keep the slide lock from being engaged or pushed up properly by the follower.

I've had similar problems with several guns, and replacing either the slide lock spring or the mag springs generally fixes it. I'd try a new mag or mag springs before anything else.
