Any one experienced with both the XD Sub-Compact 9mm and the XDm 3.8 compact 9mm? I want both, but can only get one. My intent is to wear it everyday in a(n) IWB holster. I have a XD .45 service model and love it... so I know I am going with XD for my carry weapon. I have my own pro's and con's for both, but wanted your input for my final decision. Big ticket is, is the XDm worth the extra $100+? Any advice appreciated.
