Conceptually, I like the idea of the moon clips (both third, half, and full). At the moment, I am looking at a S&W Model 610, which pretty much requires the use of moon clips. The problem is, as long as I remain in NJ (moving isn't as easily done as said), any loaded magazine or clip that can be viewed as an integral part of the gun that is in your possession is considered a loaded gun, and you are subject to a mandatory PRISON sentence of no less than 3.5 to 8 years for each device in your possession. While I would be safe in my home or at the range, I would be fair game when outside of my residence. The advantage of pre-loading the moon clips would be lost. As an aside, loaded speed loaders (which are not an integral part of the gun) are perfectly legal. Now if they only made 40AR and10mm AR ammo!
