Harwell ProTuck IWB. Carry everyday and barely know it's there.
I have been using a Kholster IWB for two years, the retension now is a good as when it was new. I recently bought another Kolster IWB for my new Beretta PX4 fullsize Storm. They provide great customer service. If your order confirmation says it will ship in two weeks, it will be in your mailbox + or - 2 days depending on the weekends. I also have a Fobus paddle holster that fits the 709 like a glove although I almost always use the Kholster.I use a Blackhawk IWB holster, size 5 fits perfectly...
