I bought one, and a 9mm at the same time.
both are too heavy for me to carry, but I have got rid of both already.
Took both to FGC, for a quick range session.
The 9mm, snappier than the 45, I liked the 45 very much, recoil was less, i like the heavier hitting bullet.
BUT, ammo is expensive, and I just decided to keep everything 9mm.
If I did get a 45 range and cerry gun, they would be XDm 45 SC and XDs 45.
I liked it that much.
