I’ve come to the conclusion that unless you are traveling and want to prevent someone from using a firearm against you on the road, gun locks are pointless to keep on a firearm.   As a matter of fact let me revise my opinion.   Gun locks are a waste of money and do not make your firearm more safe.  The traditional two piece gun lock the locks inside the trigger guard if  not absolutely rock solid tight can still cause a firearm to shoot if bumped.   What’s the frickin point of that?   Keep the gun unloaded and store the ammunition in a hidden place.  If the point is to keep children away from them, put them in a safe.  If you are concerned about theft or fire damage, get a gun safe.

With the advent of Biometric technology, many reasons for not locking up a firearm are now over.   I think  you are asking for more problems if you leave a loaded gun in your home and it is not in a safe.  Guns can get used against  you and children know how to get into things when Mom and Dad aren’t around. Gunvault gun safes are more diverse in application then from years ago and I have a few Biometric safes that are holding up as advertised.  They work great for keeping money and jewelry in and the Nanovault NV 100 is something I travel with.
