i was in the same boat as you, being a left handed shooter, and i have 2 of the range kits (9 and 40).
i went to blade tech's web site and ordered a left handed holster directly from them.
holster is great but i got owned on the cost of it.
between the shipping and the conversion and such i ended up paying triple what i was expecting.
then last year i was in Edmonton and hit Cabela's and was able to pick up a couple Blackhawks and i think it was a uncle mikes and some other brand as well, all of them where like $20-25 each.
so save yourself some money and hit a store.
OR
ive seen on eBay you can order these plastic stuff that you heat up and form around your gun to make your own custom fitted holster.
i think i may try that stuff, looks kinda neat.
