...I'd like to build a small, single shot pocket gun, something fairly compact that I could use for, well, a pocket gun. I'd like to make the bore axis as low as possible, just for the idea's sake of it, and what I'm thinking is that if I make this striker fired, and use a rimfire round, I can run the striker channel immediately above the trigger and have it hit the top of the rim, essentially meaning the bore axis would be level with the top of your index finger. I could be wrong but this would in theory mean that there's more push and less flip (as if it matters with a single-shot) but would also require less of a grip surface due to a lack of torque.
Anyways, I'd like to have something more effective than a .22 mag, which is afaik the largest rimfire still in modern production. Is .44rim still in production anywhere? Any unusual rimfires around that I'm forgetting?
The rest of the details... I'd like to use a spring-tensioned "keyed" barrel that would simply slide down into a dovetail-style slot in the front of the reciever, with the latch on the reciever and a little section of the barrel raised to take the latch and serve as a small sight. Both parts of the sight would be on the barrel meaning if there's movement or wear to the barrel-reciever junction it won't change the aim point. The striker assembly would be simple enough... sear angle would be made unimportant because I have an idea for an active disengagement system.... the trigger bar acts directly on the striker, but is moved off the "sear" surface by an angled groove cut into the reciever. As the trigger is pulled, the trigger bar both pushes the striker back against it's spring and begins to move downward off of the striker by the groove. I think it'd be consistent and it wouldn't take up a lot of space. I figure to have the striker end emerge from the back of the reciever to save space too.
I need to play around in CAD, if my license hasn't expired. I think this is not only workable, but could be done with minimal machining and nothing I've imagined so far requires great amounts of precision, except the dovetailed barrel-reciever junction. (EDIT: and the sights themselves)
I may post sketches later this weekend if I can draw one up that's not embarrassing as to my drafting skills
