I’m not a fan of magazine disconnect safeties, and I’m a LEO. I carried a S&W 4046 for two years on duty and was happy when we switched to Glocks. The old drop the mag if you think you’re about to loose your gun is not as easy as you think it might be.
It is much easier to cause a failure to feed/cycle, drop the gun and go to your backup. This is easier to do on a striker fire pistol then one with a hammer. You just place the thumb of your gun hand on the back of the slide, apply pressure and pull the trigger. This will cause a few things to happen. First, the gun will fire and the slide will not cycle. The empty cartridge case will stay in the chamber. And no, you thumb will not be hurt.
Secondly the bad guy will break contact or continue to fight. If he continues to fight, let go of the gun. While he’s trying to figure out why a gun that just went bang , will not go bang when he pulls the trigger, go for your backup and end the fight.
If the bad guy breaks contact when the gun goes bang, all you have to do is step back, rack the slide and end the fight.
The Magazine safeties was invented for people people that need extra safeties.[/QU
