Force or stealth

[MCavity]

So force or stealth?

Post SHTF it looks like most of us will not be 100% self- sufficient for food & water & meds & fuel etc etc, so unless you can barter or fill in the gap somehow raids may become a necessary evil.
I fully understand it’s not for everyone and it would be a last resort for most even if they could. If your only option would be to break into say a warehouse to have a nose around which path would you choose?
There has been mentions of lump hammers / jemmys etc in bug out bags showing a need for force, but with these products around…

….would a less noisy approach be better?
I know it would depend on the situation etc, but as a general idea the ‘gun’ looks to be lightweight / easy to conceal & cheap?
Should this kit be a standard prepper item?
