Underhammer boot leg pistol

They are indeed intriguing. They also were popular for duelling, the normal duelling pistol side hammer and nipple are in your vision when aiming, its off-centre motion and the exploding cap are distracting to the shooter. Unerhammers were less popular on rifles where you had your off hand and the grip in a vulnerable are, and it could not as easily be fired prone where the hammer might catch on surrounding materials near it. Some came with an optional forearm which made it a bit easier. Target sights and optical sights were also available.
Some pistols had trigger guards that also enclosed the hammer to help keep it from snagging. They also came in breech loaders!

And the Ultimate underhammer is a pre-percussion flintlock - how it works without the priming charge falling out, I have no Idea.

When the under hammers came out, duelling was however dying out in the States.

If cleaned and loaded correctly and consistently, they were quite accurate at pistol ranges, a .36 with a conical projectile is essentially a .38, a calibre still in use by police and world military inc. the USA with its metric disguise of 9mm. The 9mm, .36, .357, .38, are essentially all the same diameter, the cases are different for different powder charges and loading/ejection.

The breech loader underhammer was .58 cal. & originally fired a greased minnie-style conical projectile using a paper cartridge. The pistol uses a 40 grain chrge, the Rifle uses 140 grains and kicks a bit.

This is the best book on the subject.

For an enthusiast-collector of American firearms, these are rather inexpensive and not as desirable as most other firearms of that period. I don't know why, as they are all well-made, and full of character. I had one that I sold, and it took a good three years to find a buyer. They must have been quite popular in the mid-1800s, judging by the numbers extant.
I believe the interest today comes from the local collectors, as most of these were made in New England.

Oh, ye of little faith!

Not only were there underhammer flintlock pistols, but there were rifles as well - tho not as popular for offhand shooting.

Try an internet search for "underhammer flintlock".

(I used Google - lots of images too)

Appears they started making them mid 18c.
They work. In spite of gravity.

I found a gun oriented forum thread where a reply to another sceptic indicated the poster, initially sceptical himself turned his 'normal' flintlock upside down, and successfully fired it! (well, 3 out of 5 tries, once he got used to it, and experimented with a larger/finer priming charge, it fired every time.)


I gather that when the flint displaces the pan cover, kept closed by a spring, the sparks are being sent in all directions and actually ignite the falling prime charge faster than 'conventional' locks.

I noted in one photo the touch hole was at the bottom, er top of a fairly deep oval recess, providing room for a larger charge. With the rising heat, larger charge, you get a bigger ball of flame and burning powder, which as I noted earlier, going off over your offhand arm supporting a hand guard might be a bit uncomfortable for the arm. Not so much if you fire resting the barrel on a support, like a tree limb. On the other side of the equation, keeping that lock and the ball of flaming powder and smoke out of the line of sight improves accuracy.

When they had the infrastructure to mass produce percussion caps, they did become a lot easier and more reliable

Well, search duly completed. The truth is, we do learn something new every day. Gravity can be beaten by a spark.
