X2 on all 'it will fit ok' comments. The one I tried worked Perfectly. That is my next investmentThe XDm, being slightly slimmer in the exterior area of the "guide rails" on the slide will fit in all the previous XD hoslters, but the XD's will NOT fit in the supplied XDm holster because of that slight extra external width. You should be able to use any previous XD holster with your XDm in my opinion. All mine are usable and retain the gun just fine.
Should fit either without any issue. Congrats on finishing your class...and congrats on the new xdm!:mrgreen:I just recently purchased an XDM 9mm, and I also just finished my concealed carry class/applied for permit. This may be naivety, but if the holster fits the XDM 40, would it also fit te XDM 9? or do they make different holsters for different calibers of each model?
