Hello Fellow Knoxvillian,
I have several Bianchi holsters, however I don't have the one you are asking about. The only words I can offer is that, if you are going to be doing a lot of twisting and turning and bending the spring clips can and will move around on you. I have a mag carrier by Bianchi and a much cheaper holster made by BagMaster. They both are the steel clip and both do as I said in that they can relocate and in some case turn loose of the belt. I believe that I would rather have something a little more firmly attached to me. See if the S3 Pistol Pocket, also a Bianchi product is available for your weapon. I have one of those for a snubnose and it is a fine IWB holster. You might also look at their model 7 which is a pancake style. I carry a GLOCK 21 in one of those and it also does a fine job.
Regards P.T.
Ps
Check with Craigs up towards Seymore and Greene Military Supply for your Bianchi. I have bought from both places.
