I'm not sure the specs shown on the Eagle Imports site are 100% accurate, because they show the 45UC as being .1 inch narrower than the 9UC, and I just don't believe it.
I own both guns, and the 9UC grip feels slightly smaller in my hand than the 45UC. But the 9UC has finger grooves, and the 45UC doesn't, and I think that accounts for the difference in how the guns feel in the hand. I believe the grips are about the same as far as thickness side to side, but the 45UC grip is slightly thicker front to back. Not a lot, but enough to perceive a difference when holding the gun.
And here's something I just thought of. The Firestorm Mini 45, made by Bersa is nearly identical to the 45UC, but has finger grooves in the front strap, just like the 9UC. I'll bet it feels slightly smaller because of that.

I'm no expert, I'm just, well---opinionated!
