Luger / Walther 9MM to .22 Conversion unit

[Vlim]

I'm not near my guns at the moment, so I can't take a detailed look. I did manage to increase the size of the photo of the conversion fp, you can see it even has a small rubber seal around the middle.

IIRC it is spring loaded inside, so a flat base the size of a primer that pushes against the smaller .22 pin.

I suppose the O-ring is just so the adapter won't fall out...

The spring-loaded part puzzles me...Does the spring push the 'firing pin' backward or forward??? It looks like the 'pin' is sticking out of the front...So if you pushed the adapter into the 'chamber', it would push the spring-loaded 'pin' back...

That's where it gets foggy...The pin can't be too big in diameter or the breechblock closing would fire it (instead of the Luger firing pin hitting the adapter pin)...

I was thinking of an angled firing pin...But maybe a 'Z' shaped firing pin, in a slot milled in the side of the adapter???

I'll try to find the patent drawings...I can think of a couple ways to make the adapter/firing pin, but they would all fire when the breech closes...hard to aim that way...

Maybe Gortz & Sturgess have information on it...Yes, they do!

But where is the spring???

Hmmmm...Ken's 'kit' is for .22 shorts [Model 151] while Gerben's is for .22 LR [Model 1-70]. The cartridge adapters are not the same.

Ken's Model 151 also has an extended portion with what look like soot-marked holes in it...

I'm getting an idea of how the .22 LR cartridge adapter works...Unfortunately, it's 'micro-machining', which is pretty much beyond my skill/tool level...

Edit: Found a couple threads over on WaltherForums detailing the .22 & .177/sub-caliber adapters and the trials of members there dealing with the eBay seller...
