only difference between the service and tactical is the length of the barrel and is not the concern until you start trying to pull out 10'' desert eagles and 500 s&w's and bfg's like that in the xd the grip is the same size thats the part to work on concealing. unless in a shoulder rig or something like that even then not much difference. you should be fine just work on concealing that gripWhat about a XD-9 Tactical 5"? I'm 6'1" hopefully that helps conceal this massage beast. I don't have my CHL or CCL or CPL yet.
