Worst advice? Man at gun counter in box store says, “Try this on. How does it feel?” I hate that one. I know a lot of really savvy and helpful folks working the counters, but ones that say that nonsense make the rest look bad. You’ll get used to the weapon with time as long as the controls and parts are situated correctly for the size of your mitts and your digits.
Worst action? “Veteran” shooter takes newbie out to the range and loads up some monster .44 rounds in his magnum wheelgun, snickers while watching, and tells his buddies about it for years… That one really starches my shorts. What they’ve done is potentially robbed somebody of their desire to join us. By extension, they’re rationally far less likely to ever go down the road of carrying for self defense and protection. I would never knowingly take that from someone, but those are the common ramifications for acting stupidly.
Runner up worst advice? “Get yourself something small and easy to conceal…” Ugh… Let’s pick the right weapon first, and we’ll figure out a way to conceal it second. That may seem odd, but it is a better order in which to place those two things. Besides, pocket rockets are like a frag going off in your hand anyway, so the idea someone new will go practice, take a class, or continue any kind of education with one of those is largely false…
There are more, but you guys catch my drift I’m sure…
