Valnar,if physically pointing a rifle at a man that came breaking through my front door(after a brisk exchange of punches) constitutes deadly force then I have been there.
But that break in,and it was a home invasions by any count,was over a woman and not my worldly goods.
As far as my gun safe being breached the answer is no.
I have had the home I live in broken into three times in 30 years though and have had numerous firearms stolen because they were not locked up in a safe.
I live in Houston and can tell you Houston averages 60 home burglaries a day which is more or less 1800 a month.
So since probably at least one out of three of those homes has guns in them a lot get stolen.
I have what I consider a pretty good gun safe which some call a RSC.
I also have a fair collection of pictures of gun safes that have been pryed or cut open and most are lower grade units that have 12 gauge bodies and thin,flimsy,"composite" refrigerator type of doors.
And if these guys have real power tools they will cut right through a certain safe salesmans 1/4 steel wall Graffunder "safe" almost as easily as a Chinese 12 gauge "safe".
But most RESIDENTIAL burglars do not carry power tools.
So always remember that even though a 12 gauge Cannon,Liberty,Champion,Browning may be an UL rated RSC so are my Amsec BF,a Fort Knox Titan,a Liberty Presidential,etc. and they are much more robust than the lower tier RSC's as far as a prying or beating attack is concerned.
And of course that 1/4 inch walled Graffunder is even better than the others I mentioned under this sort of attack.
The truth is not all RSC's are created equal.
Hotshot,the LG means Lagarde lock.
