I was holding a 610 in the store a week ago. In double action I had to reach a little far for the trigger but the trigger was perfect in single action mode and the single action trigger pull was surprisingly light.While I don’t own a XDm in 10mm, I love my S&W 610 in this caliber,
I searched for a couple months and then one showed up in a LGS I got the compact Elite without the Hex and just purchased a Holosun 507CI was able to order mine from a small dealer pretty quick. I also stopped into a local store and they had the XD-M Elite Compact 10mm (but without the Hex) so I was able to hold it before I ordered it with the Hex. They are out there but go quick I'm told.
