Now, don't get me wrong, I'm not defending magazine disconnectors. I have pistols that have them, and others that do not. I'm saying that I would not take it upon myself to "alter" the safety features that the factory installed on a firearm. Trust me, it will create an "issue" should that firearm be used to shoot someone.
In my early practice (I'm now 60 years old and semi-retired), I assisted in the defense a fair number of product liability cases (civil actions). A couple of those involved firearms. I can't recall the exact cases, but the operation of the safeties and whether the firearms had been "modified" by the owners were significant issues in those cases.
You might want to check some of the writings by Massad Ayoob, although some think he's a bit of a "bag of gas." Nonetheless, over the past 20 years I know that I've read articles where he discussed the issue of altering or modifying firearms and how that came up when he was testifying as an expert witness. IIRC he cited to specific cases on more than one occasion.
Look at it this way, if you ever find yourself on the wrong end of a prosecutor or plaintiff's attorney regarding a firearm incident, he will be "shooting" at you. Now, he may miss. But, I see no reason to increase his chances of a hit by providing him with more ammo. FWIW
The bottom line is that if some folks are hot to remove the magazine disconnect, they probably will. And, actually, I don't really care because they're not my clients.
