No some guns will feed from any mag, some will only feed from their own brand, some will require the mag to be modified. There is absolutely no hard and fast rule and varies from gun to gun even made by the same manufacture. Only thing that can be fixed on the fly with out real knowledge and experience is barrel blockages. Even if you are technically proficient I would highly recommend not trying to open up your gun and site, that's asking for a part to ping off in a random direction never to be seen again
