Default Idea for P80s... dimensionally complaint break-top/open single-shot pistol

So I could be wrong here or missing something but if you wanted to legally make a Polymer 80 or similar gun into a single shot handgun first, I think the answer is in the spring and guide rod.

This is assuming you built your lower and have not attached a semi automatic upper yet.

When you go to assemble your upper, insert a round into the barrel (snap cap ideally), then insert the chambered barrel into your slide. With just the guide rod and spring remaining.

With the guide rod and spring there are two options.
#1- insert a spacer into the rear of the guide rod so the spring can only slide back 1/3” it’s normal travel distance or insert a longer spring which essentially does the same thing. Goal here is to limit the amount the spring can contract.

Install the slide on your lower and pull back the slide. Ensure you can only pull back the slide enough to reset the trigger-Not extract or chamber a round. If you pull back the slide 1/3-1/2” it should be enough for your trigger to reset but not extract the spent round (even if it did extract the round, it shouldn’t open big enough to load a new round.

Because the slide retracts just enough to reset the trigger, go ahead a take down the slide after you fire a round. Pull the casing out of the barrel, insert a new one. Put the slide back on, repeat.

This is single shot. It would also require you to breakdown the firearm to remove the brass and load the next round.

If you wanted to convert it to semi auto after you have built it, just remove the spacer in the guide rod or change out the spring.

I am sure I am missing something but I just tested this on my Glock 19. This is does make it single shot for sure.

What do you think?

It still needs to meet the length requirement.

There is no legal way to convert to semiauto in California.

To your first point, it is easy to throw a long barrel on it.

And if you did do that, I think you accomplish the goal if creating a legal single shot handgun... right?

There is no problem in the creation of a single shot pistol, there are ways to do that.

The potential problem lies in the act of converting the single shot pistol into a semi-automatic one.

One interpretation of the law - reasonably well founded in legal precedent - holds that going from single shot to semi-automatic is itself an act of manufacturing, and thus against the law.

This interpretation is not yet the clear interpretation of law in California, thus my caveat of "potential problem". I'm not a lawyer and have no advice to offer regarding this issue.

From what I have seen the issue is the step from single shot to semi-auto and the CA PC which prevents it from being done in CA. It seems that it would have to be converted outside of CA, then brought back (which could be an issue too).

Assuming you had a legal way to convert your single shot pistol to semi auto the process I listed above would cost you approx .30 for a plastic spacer. Granted you would need a long barrel as well.

In order to be considered single-shot, the firearm can never have been semi-auto before being made as a single-shot. [PC 32100(b)]

Using a factory made complete "upper" (slide/barrel) would be evidence that the firearm was once semi-auto (since they are tested at the factory as a semi-auto).

Therefore, the single-shot "upper" (slide/barrel) must be made from individual parts.
^Can't use factory made semi-auto "upper".

P80s are not Factory so you should be good on that end, especially if you’re buying an extended barrel and aftermarket slide
