Old post on my dislike of Magazine Disconnects. I consider them a “Safety Device” that makes your gun MORE dangerous, and potentially something that could disable your gun when you need it most.
The idea that dropping the magazine on a gun makes it “Safe” encourages lax gun handling, and adds the bizarre scenario where one would take a “Safe” gun and insert an empty magazine (A step I might add is necessary in many guns equipped with this feature for things like disassembly and dry fire) and if you have not properly cleared the firearm (the whole argued reason why a Magazine Disconnect is a rational idea) your “Safe” gun will now fire a single round when you pull the trigger.
That and having your mag not properly seated, or bumped loose will now make your defensive gun a brick until you remedy that.
YIKES!!! I haven’t spent much time rooting around in the guts of a hi-point, so I don’t know how easy it is to induce this malfunction in less extreme conditions. I have monkeyed around with the disconnect on an M&P and I will say that the disconnect is pretty protected from pocket lint and random debris….but if the gun was dripping with mud or grit (or snow in a cold environment) and the action is cycling I certainly could see sand, grit, or some ice gumming up that device….tho thinking about it, on the M&P it might be more likely to jam the safety OFF….that’s really what I did to disable mine, I removed the cam track that engages the trigger bar when the disconnect arm is moved by an inserted magazine, and jammed it closed with a sufficient spring.
Either way, we as gun nuts need to be sharing our knowledge about these “Safety Features” so that people can start thinking about them as terrible ideas, rather than good ones.
