I bought a N82 tactical professional holster for my 9mm Shield and have found it also works for the 45 Shield. I wear it at 3 o'clock strong side hip with slight cant forward.
Just wanted to add an update. I have my 45 shield now and the N82 holster I purchased for my 9mm shield works with the 45 also. The barrel does protrude past the end of the kydex but the retention is still good. No new holster to carry my new EDC cannon.
Check out N82 holsters. N82 Tactical Holster Options | N82 Tactical. I have been carrying my sheld 9mm IWB since April and is truly comfortable. Yes I know it is there but it is not annoying. I have the "Professional" which is also a tuckable IWB holster. It is comfortable against my skin...
