When I used to own centre-fire semi-auto pistols (in the days when you were allowed to), I used to carry them to the range in a shoulder holster. The reason for this was that I wanted to have it on my person at all times. The police consider it very bad form indeed to have a firearm nicked from a car whilst you're in a petrol station or cafe. A shoulder holster was the most comfortable way of carrying sitting in a car, and is more discrete than a belt holster.

Yep me too,and was stopped by the police on the way to the range. They had no problem and could see the logic as I was on a motorcycle.
I also regularly carried a section 1 shotgun a 10 shot remi auto,in a bag slung across my shoulders.
Those however were the days of common sense and discretion,not the world we live in now.
