From what I've read about the MA/CA compliant Magazine Safety, it just prevents the gun from firing without a magazine in the pistol, so that the gun would be rendered useless, even as a single fire weapon with one in the chamber, if the magazine was removed and hidden.

Can that be removed, both physically, and legally? Even with it in, can I "jam" the mag into the pistol with a full 10 in the magazine, without hammering the inner mechanisms of the pistol? I didn't try to force it, but if I hear that it won't cause damage, I will try.
