For me working hard (for example, climbing onto and under vehicles) is still a niche for a pocket revolver.

I've been carrying a Beretta Jetfire as backup / pocket gun and for the first time after years found the mag had popped loose after having been under a vehicle. That's happened with several other autos but this was a first with the Beretta and its anti-accidental release button location.

Back to the LCR for that role.

Many years ago I relied on a NAA Mini .22 mag for the same purpose but decided a knife was better than the slow, clumsy mini.

How about you?
