Not me but if you take newbies to a match, please:
1. Give the correct magazines for the gun you lent them. Nothing like seeing some beginner with a gun that won't fire as it has the wrong mag.
2. Get the newbie a decent holster. Not some weird horror that has a mag pouch in front to the gun part, so that when the beginner has to reload, they have to reach across body - what a mess.
