Blackhawk Serpa paddle is a good one if a "plastic" type holster works for you. Adjustable cant, good retention yet easy to draw from. They make one for the G36.
on a side note: This holster will not work on 1911s. When you snap the retention strap, it will take the gun off safety. I called Bianchi about this and they told me that they do not design their holsters for "cocked and locked" 1911s. So now they want users to manually de-cock and then re-cock if they need it. This is backed up by a statement on their website.
