My brother and I came across this item at our local gun show this last weekend. This product is a workable solution to the problem of keeping a loaded gun available for instant use while also being safe from accidental discharge. Many states and localities require that all guns in any home be disassembled or locked up when not in use. Grabbing your gun and the finding the key for the trigger lock at 3AM requires more time than you might have if someone is crashing though the door. On the other hand, having a loaded handgun in your house unprotected is a risk to small children and idiots. It could even be dangerous to you if bad guys were to get to your weapon before you do.
The idea is quite elegant. If a safety bullet is fired, the small primer charge expands a plastic wedge in the barrel and locks the gun up. The slide won't move to eject it and removing the magazine is of no help. The gun pretty well becomes a paperweight. The idea is to keep one in the chamber so if someone simply picks up the gun and pulls the trigger, the gun is a paperweight. If they rack the slide to chamber a shell, they eject the first one and load the second one. When they pull the trigger, the gun becomes a paperweight.
When you need the weapon to truly fire, you cycle the gun twice and the two safety bullets are ejected. Now a live round is loaded in less than 2 seconds and you can defend yourself. There is no key to find, no box to open, no odd procedure to remember, just rack your gun twice. The makers tell me that the device complies with the Child Access Prevention laws of all states and is patented.
The pair of safety bullets is sold with a device to remove a triggered round with no harm to the weapon in about 2 seconds. Available in 9mm, 38 caliber, 40 caliber and 45ACP, the two safety bullets and removal tool sell for about $25. The website, http://www.safetybullet.com can sell to you directly, or you can look for a local dealer. Safe and effective is as good as it gets.
