I've got one coming to me for my 1911, glock and HK USP.
the springfield one should fit the others, as they advertise for springfield since they have the more squared off dust covers-besides, most of the retention comes from the trigger guard area...
I can't wait to try them out.
you can-you can purchase an additional paddle that bolts on and gives approx 15 degrees of cant. you can also bolt on belt loops if you prefer that mode of carry.
can't wait to get mine-I hear great things about them.
for the $$ it is a good compromise between fobus/uncle mikes and blade tech/mad dog.
