I’m by no means a gun expert, or enthusiast so I’ve never seen one like the red-gripped one in your picture. It almost looks “other-worldly” - like a “ray-gun” or Han Solo’s Blaster! ;) What kind of gun is that, if you don’t mind my asking?
That’s a Para Ord. 1911 LTC (barrel is 1/2” shorter than standard).
If you mean the one on the lower right, that's a Ruger Mark III Hunter in .22 LR with very pretty cocobolo grips.
