Just dunk the holster for about a second,,,
Because nearly every holster maker tells you not to do that.
I'm a long-time holster maker and I disagree with the above statement.
But here is what may change if you wet-form the holster:
The color of the leather might alter a bit to be darker,,,
Sometimes metal rivets and/or snaps will form a bit of rust,,,
You can over-wet the holster so that it will lose what form it had from the factory,,,
First off, wrap your gun in about 5 to 6 feet of Saran Wrap,,,
Then fill the sink with water and dunk the entire holster
for a second or two,,,
Then pat the excess water off of the leather with a cloth towel and insert the wrapped gun.
Work the gun in and out of the holster several times over a few minutes,,,
That creates the "channel" the holster will drop into,,,
Then simply let the holster dry for the night.
Don't "soak" the holster,,,
Don't let it dry without forming the channel,,,
When it's completely dry (24 hours) apply a
tiny amount of any leather conditioner.
I've done this for customers so many times I can't count them all,,,
The one and only time I ran into trouble was with a cheap un-lined holster,,,
The water-based dye they used was only a surface coat (paint) and it dissolved in a few places.
I had to scrub the remaining dye/paint and recolor the leather.
Good luck,,,
