I want to dry fire without a magazine in the gun. Seems too easy to end up loading the gun if you have to have a mag in it. Or more likely to think it's unloaded when it's actually loaded sine you are used to seeing mags in even empty guns.
Plus with empty mags locking the slide back, cycling the slide to dry fire repeatedly seems pretty annoying.
And it's another part that could fail or go wrong.
If not for the above, and if it didn't alter trigger pull at all, I wouldn't mind it. It DOES have advantages. For example, if you get into an altercation and may lose possession of the gun, you can drop the mag and it will be much more complex for the other guy(s) to make the gun function. I do see that as an advantage given that the mag disconnect is very difficult to accidentally activate (I have yet to accidentally activate a mag release myself).
