Sedgley OSS .38

Y'know my least favorite part of Pavlov? You can't punch anyone!
Recently, I've discovered a real life weapon that could solve this very issue. The Sedgley OSS .38. A World War 2 era pistol that mounted to the back of a glove. If you punched something, it'd immediately fire a single bullet.
How is this useful? Well, it barely is. It would pass on cool/fucking stupid factor alone, but for the sake of convincing you further, imagine this.
You're playing some kind of game where there really aren't many rules in a large map. Someone with better guns than you tells you to drop all of your guns, you comply. They come over to take your stuff and BLAMO! You've punched that dude in the head! And thanks to your Sedgley OSS .38, you've turned his cranium into a fine meat and skull salad. (I also imagine the gun camouflages itself to the color of your gloves, for added sneak factor)
I hope you'll take this into consideration, but I fully understand if you're too afraid of God's gift.
Thank you.
