Sorry if this offends, but that revolver is a novelty item, not a defense tool.

Remember the velocitys, and balistics often quoted for .22 cal., are taken from rifles - not 1" barreled revolvers...

Although I would not discount the damage one of these could inflict, I would not consider one as an offensive weapon (where all is in your favor), much less a defensive weapon.

As to reliability, I have had to replace parts on a good number of these, not ALL revolvers are dependable. If you shoot one of these enough to become proficient with it, I see a few trips to your local gunsmith.

All that said, I do wish some company would (at - last) market a good "pocket gun", for defensive use...The best to date IMHO, was the remmington .41 Derringer.(often copied, never equaled)

As to use for hunting application:

See above., save the weight on the 100 rnds, and carry a can of sardines - then you'll have something to eat <img src="/images/graemlins/grin.gif" alt="" />
