What pistol are you having this problem in?
I doubt it's the magazines.
Without a magazine inserted & with the slide locked back, have you tried tapping the butt of the frame on a hard surface to see if that releases the slide? It shouldn't.

That behavior is not correct for a Model 915. Things that immediately spring to my mind. Slide stop or very worn/damaged slide stop cut in the slide. S&W slides are pretty hard, so I'd look at the slide stop as the first suspect. Maybe it something real simple, like the detent plunger in the slide stop is stuck from dried oil and gunk. It could also occur if the sideplate assembly was damaged and the detent was no longer making the correct contact with it.
Range report - pulled the gun apart and did an extra good cleaning around the detent plunger problem went away. Also cleaned the mags and followers. One strange thing I've noticed with the 915. During reassembly, I sometimes get to the point where the slide stops even with the frame and can't move back any further to put in the slide stop pin. Usually the fix is remove the slide, take out the barrel and the recoil rod and spring, put them back together and everything goes right back together. For the life of me, I look at the barrel in the slide and the recoil rod and spring and it looks EXACTLY positioned as it did before when it wouldn't slide all the way on....
Thanks for the advice.

Had that happen on my CS9 last week. No real rhyme or reason to it, it just happens. I'd guess that with the tight tolerances they use, even a tiny bit of incorrect positioning can cause things to bind up.
Almost any semi-automatic pistol will release the slide if you insert the magazine with enough force. Doing so on an AR style rifle will release the bolt unintentionally. I don't ever recall seeing or using a semi-auto pistol that had this as a "built-in" feature. A contributing factor to this happening could be dirt or worn parts, but one should not smack the magazine in place like you are trying to close a barn door. If you do this with a partially filled magazine you may even turn cartridges completely around in the magazine. Last but not least, if you run the magazine in place on a pistol with enough force to release the slide it may happen so fast that the slide can't pickup a cartridge from the magazine and you will find yourself with an empty chamber, or you could induce a jam. Insert said magazine with only enough force to lock it in place.

Glad that a thorough cleaning solved the slide stop issue. As for the reassembly hang up, welcome to the world of S&W metal frame pistols. No matter how careful you think you have things lined up, it's just not quite right and you have to jiggle things or re-seat the guide rod and hope for the best.
