No Way This Piece Of Junk Works As Advertised

 

I can see the pointed end doing damage as pointed ended weapons often do but I can't see this flint loaded pistol to be very effective unless you use it BEFORE you start swinging the axe part around. You would need to keep the gun very steady least you spill powder thus reducing the velocity of the bullets fired. Good luck trying to reload this thing when it and you are covered in other people's blood. It's seems like a good idea and there is a reason why they never became standard issue.

 

Early 17th Century Combination warhammer and warpick/six shot gun.
  
Has six barrels concealed on it for six shots.  The head contains five barrels, their muzzles concealed by a hinged cover forming the edge of the hammer. The topmost barrel is ignited by a matchlock fitted on one side of the head, its mechanism concealed by a brass plate cut out and engraved in the form of a lion. The second barrel has a wheellock ignition system, the mechanism of which occupies most of the outer surface of the opposite side of the axe-head. There is a tubular extension to the pan of the wheellock intended to hold a length of match which would be ignited by the flash of the priming and then withdrawn to ignite the three remaining barrels. A sixth barrel, also hand-ignited, is concealed within the haft.

I just read that italicized part and I have no idea what the guy is talking about.
