If you can afford to try a few different brands, a shoulder holster system might work for you.
This depends on how you are dressed when you get to where you are going.
I like them.
It doesn't take much to alter clothing for carry.
One of the easiest ways is to take an Uncle Mike's soft style holster and use snaps, buttons, etc. to create a means of securing it inside your coat, a pocket, etc.
Not knowing how you dress, here's an idea that may help.
Try a Patrolman's coat. The one with a side zip specifically for a belt holster.
You won't want to wear the holster exposed of course, but it may provide you with access to one.
For gloves, try a pair of lightweight gloves like the Isotoners that were mentioned, or a pair of 'liners', inside a loose pair of mittens. If the mittens have some of that sticky rubber on them (like the Ice-climber's mitts), you can use this to drag the mitten off your hand and still have protection with the thinner glove to draw and shoot your firearm.
