As acparmed stated reaching around the front works good. I carry at the 3 o'clock position with a forward canted holster.
If you grab the grip and pull the pistol just out of the holster and press the slide against your side you can roll it around for a good grip pretty easily with some practice. I do practice this when doing daily practice draws (about 40 - 50 draws on average) and dry firing.
