Gun carriers don't normally walk around with their six-shooters lashed down. Holsters in those days weren't as form-fitted as they are today, and would allow the guns to fall out. THAT'S what about it.
I get what you're saying haha, there's a reason why I have watched almost all of Roy's movies and this is one of the last ones I haven't watched... 10 minutes in and I already want to go watch a different one!
