Finally received the Thunderbird Defender on December 23rd. It was ordered on July 17th. It is a well made holster, but I am going to have to get used to the IWB way of carrying. I also will have to get a larger size waste for my pants and a better belt. The holster can also be worn OWB by removing the belt clips and threading a belt in the loops. These loops can be seen behind the clips on the third picture down showing the back of the holster.
Any questions, just PM me and I will try to answer. This is my first day a of trying it out.
