Jay,
I realize that this is an old post.
Yes, I have an XDm 3.8 40cal and Love it.
I also have 2 Service models of the xd.40. Love both of them as well.
I had Springer Precision install a set of TruGlo TFO sights on my 3.8 xdm, and do a trigger job as well. Both are outstanding. Scott at springer precision does Awesome work. Very good People.
I carry in an IWB ROG holster. Richard at ROG Gunleather is also a great guy. I have one of his older IWB holsters, and now I just purchased 2 more from him for my xdm 3.8, and my boys gen 4 glock 22.
The Quality and Craftsmanship on these holsters are Awesome. Richard uses Herman Oak leather.
I purchased my xdm 3.8 40cal., right after they came out the first of this year for $565.00 and that included the phone call.
Do you have one, if so which model?
Sorry this is a late post brought back to life, but I have not been on this site for awhile.
Stay Safe.
