Hopkins @ Allen UnderHammer Pistol Grip.

[John May]

Hi All. I recently purchased a H&A UnderHammer Target Pistol and have a question regarding the grip. My example has been modified for 'Free Pistol' shooting and the grip is now a crude orthopaedic copy.

My question is, did these pistols originally have a Thompson SMG grip fitted or is this a popular urban myth?
If yes, then I may be able to purchase one here in the UK as I would very much like to convert it back to its original state. Thanks in anticipation!

I believe the Thompson story to be fantasy. Since the H&A design is so simple (that is the beauty of them), I suggest you could carve a grip to suit yourself.

Numrich (Gun Parts Corp.) owned the Thompson name and was building full auto Thompsons at the time and also semi autos too. The H&A grip was a modification of the Thompson but you couldn't make an H&A grip out of a completed Thompson grip. Rifleman 1776 is correct in that you could make a grip very easily and one that would suit you.

I have an old black powder digest from the seventies I believe it has pictures of the original H&A pistol grip if so I'll try to take pictures and post them

It looks like it could have come from the same blank used to make a Chicago Typewriter grip... but i don't think you could swap one for the other.

Okay, compare these photos:

Note any resemblance?
