With the benefit of some of the wine that returned on the trip and some ceiling staring I reckon the pin broke from a restriction of travel rather than an excess of the same. The snapcap I used has a rubberish flag pinned in the position of the firing pin which stands a half mil or so so high of the shell face. I think when I smashed the bolt closed and pulled the trigger the firing pin didn't get to clear its normal range of motion and was moered kwaai on the rear of the retaining pin slot by the firing pin retaining pin.

It happens to most fathers who have to leave their daughters in big, bad cities to fend for themselves 😉

Seriously though, I hope you find replacement spares.

You should probably write nelow the sketch, "Drawing not to scale".

Yip as well as 'and dimensions not to be trusted'.

I'm sending the original to the smith to duplicate.

Do you even need a snapcap for dry-firing the high standard. i know the Ruger Mk IV it is not necessary. The pin cannot impact anything hard if the chamber is empty.

The broken pin isn't from a hi standard pistol it's from one of their 12G pump actions. I also have a hi standard supermatic citation .22 pistol and if you dry fire it without a snap cap it impacts the rim recess which I confirmed with some carbon paper. I have a bunch of solid brass snap caps in its bag. My rule of thumb is to use snap caps with anything that isn't of fairly recent design as support for dry firing without damage wasn't a given even into the 80's. Half of my guns predate me so I use a lot of snap caps.   

I contacted a gunsmith who I've used with success over the last 25+ years to quote me on making a new pin after I found that importation was going to be way too much PT. Their price was stiff but able to be swallowed with a bit of a whisky chaser so I sent the broken part to them. On following up yesterday they bombshelled me with an expected delivery date 'hopefully by the end of March'. Bloody hell it must be nice to be that busy! 

It helps to have a tame machinist in your rolodex.

From the little experience that I have, the best gunsmiths started as well-trained machinists.

I had one but he passed away some time back. Also had an independent one man band gunsmith who would have knocked this out in a few days at most but he emigrated to the US. I've always wanted a lathe and this was very nearly the trigger for it but I spent more money on my daughters varsity expenses to make the feeling pass.

Got good news in that I was bumped up the queue and my firing pin has been made and delivered to my office. Will pick it up shortly and hopefully get to shoot the shotty a bit tomorrow to see how it runs. All in the pin cost more than two thirds of what I paid for the gun so it no longer seems quite as much of a bargain but I'm glad I got it none the less.

I now have two of High Standards products, namely a Supermatic Citation and a Flite King Riot 12G. Horrifyingly I just seen that there's one of their Model 10 frankenbullpup police shotguns on the current Classic Arms auction. The temptation is strong.

There is a sports king and a citation on the auction as well.

I saw those. A friend is after the Citation which has the optional, and for serious competitors back then more desirable barrel mounted rear sight. It's otherwise identical to mine. I'd like the Sport King but with the weights and brake off my Citation it does perfectly good work as a field pistol so I can't make myself want it enough. The Model 10 is a lus to have something weird and at the time ground breaking. 

Happy days! The shottie ran like a top. It's a lovely shooter with as smooth an action as any I've ever felt.

Seems you had a great shooting session. Both pistol and shotty fixed!!!!!!
