I LOVE my 45 Shield! It's an amazing pistol for it's size.
I've had mine for about a year, and find it's recoil to feel very 'similar' to my USP45.
It fits my hand well, and I really like the grip's texture - very secure in hand.

My only complaint is a somewhat limited list of shoulder holster options:
the 45 Shield is not available in the Galco 'Classic Lite', or the 'Jackass Rig' or either of the 'Miami Classic' rigs.
I ended up getting the DeSantis C.E.O. rig which doesn't have a mag pouch --- I don't want to $pend for a custom made holster.
The 9 & 40 Shields have more options in shoulder rigs.
