All the above is pretty spot on. they come in three sizes and calibers.
Full-size models include 9mm and .40 and can be found with and without the accessory rail.
Mid-size (full-size grip, shorter slide/barrrel) is the only size that includes .45ACP
Compact (Shorter grip, shorter slide/barrel) is in 9mm and I believe .40, I've never personally seen a compact .40
They are great range guns with a decent DA trigger and a good SA trigger. The initial few rounds might be a bit gritty, but the trigger cleans up with a judicious amount of dry fire practicing. The gun is heavy, which is good for absorbing recoil and naturally "drops" back on target. IMO it's weight better serves it as a house gun than a carry gun.
Depending on which import model you get, the name changes, but is essentially the same pistol. MR imported it as the Baby Eagle, and Charles Daly imported it as the Jericho.
Also, if you need parts or labor, the EAA witness is a very close relative of this pistol. Not everything is the same, but many of the parts are, such as the extractor.
I suppose I should add in, I own a .45 caliber model, very accurate gun, and the trigger is great in SA. The barrels in these are polygonal. Here is a helpful resource for more knowledge about this pistol:
