Great Design!

This is a very well thought out product. It’s a very fast system yet also protects from unwanted hands. Highly recommend.

Too Small

Fits my conceal just fine, but my home protection pistol does not fit in the box so it’s ultimately useless

Great retention device!!!

Great simplistic retention device! I am a new father of two awesome boys and while I will teach them gun safety I am a few years from them understanding this. This will definitely keep them safe and away from them.

Best shotgun locking device on the market

Quick, easy, safe. It’s the best shot gun locking device on the market

Great gift for a friend

Recently gave this product to a couple friends of mine, who own weapons and have stated that they keep them out and unlocked so they will be able to use if the time ever calls that it’s needed. They were gracious for the idea and are happy to maintain the same level of readiness all while safely going forward.
