Most instructors are right about the laws, but occasionally you will hear the odd thing from one that in not correct. Sometimes they take it apon themselves to express there point of views and suggestions of what to do in a particular situation. My instructor that I had for my handgun safety course told me that a El'Cheapo $89 Stack on from Crappy Tire is classified as a safe, and I don't need to use a trigger lock. I think thats his point of view, and he is sort of boycotting the law be not putting a trigger lock on his handguns, that are in his cheap stack on gun cabinet.
I know that the meaning of the law is telling you to put a trigger lock on a Restricted that is in a Stack On "Cabinet", so I DO put trigger locks on my Restricted firearms that are in my Stack on "Cabinet".
Basically, if you have a SAFE, that is labelled a Safe, then you don't need no trigger locks.
I personally believe that a Stack On Cabinet that is bolted to a wall, like mine, should'nt require a trigger lock, but it does, and I DO put a trigger lock on my Restricted firearms. However, in my case I happen to keep my Stack On Cabinet in a locked room also, so I don't believe that I need to put trigger locks on my Restricted firearms because there is 2 locks that must be opened to access the firearms.
I don't see how a small 60 lbs pistol safe is legal to keep your pistol in without a trigger lock, but a Stack On Cabinet that is bolted to the wall is not legal, but there is quite a few firearm laws that need to be changed, and we are probably better off by not bringing stuff up to the powers that be, because things will more than likely change for the worst, and they would just say that all Restricted firearms require a trigger lock, no matter were they are.
