Well first off, i just ordered a XD 40 service model, with Mepro sights. I am LEO and this will be my duty weapon. The problem im having, is i cant seem to find anybody that sells a good holster for a "street cop" to carry. Their seems to be plenty of CCW, and "dress" style holsters out there, but none that i have found have any retention devices. Any suggestions would be appreciated.
