one thing I like about the xdms is, you don't have to pull the trigger to take the gun apart. No other striker fired gun has that( that I know of anyways)
While yes its a very small thing, and if you fallow the safety rules its no big deal, but what if you have a malfunction and you need to take the gun apart.? There is als those that don't fallow the safety rules... tons of them out there.
