I will of course keep the colt. I would never dream of selling it.In that case, I'd treat it as an heirloom, take care of it, and maybe shoot it on special occasions so my kids could inherit grandpa's gun some day, especially since it sounds like it's in such nice condition.
I Have Your Answer!
I have applied mathematics to your question and have found the perfect answer.
The average .25 ACP cartridge has a muzzle energy of 64.93 ft/lbs.
Let's say that your firearm is a .25 sub-compact pistol. The average weight of this class of pistol is 13.57 oz. empty, which is to say it weighs 5,936.88 grains. If you could throw it at 75 mph, which is far slower than a Major League baseball pitchers throw a fast ball, that velocity works out to be 110 fps, and will yield 160.35 ft/lbs of energy on your target.
This tells us that you will have a much higher energy on target if you just become more proficient in throwing your empty .25 caliber handgun. (Please be sure to remove the ammunition from the handgun before throwing to avoid an accidental discharge... Safety first.)

Safety Notice - Whether it is shot or thrown, you can still put an eye out with a .25 caliber handgun!
With information listed above, I would suggest that you carry a rock!!!
Sounds like my little .22 auto might be a more effective choice given the opinions stated in many responses though.
