The more training and experience you get with a wide variety of guns, the less it matters. After almost 30 years of formal training and shooting, it doesn't make a big difference to me, but if I switch from a Glock to a 1911 and then go shoot it under competition pressure, I still have to think about the safety some to make the switch.
