I just bought the SA xd 9 mod 4. So far loving the gun. It’s my first Springfield and I’m excited about it. The issue I’m having is I am unable to find out if the mod 4 shares holster compatibility with any of the previous mods? I’ve scoured the internet looking for an answer and can’t seem to get a straight one. Why don’t I just buy a holster for a mod 4? Because I’m not really able to find one. Mod 3 and previous have a vast amount of holster selections. Thanks for any advice or input. I’m not well versed in the XD series but after handling the gun I loved how similar the ergonomics were to a 1911 so I’m hoping to make this my new edc.
