Made the recipes, spawned all the parts ingame, made the Glock switch, added it to a gun, and fired it. There's a video up on Discord that shows it working.

Additional context

[autofix-ci]

Autofix has formatted code style violation in this PR.

I edit commits locally (e.g: git, github desktop) and want to keep autofix

1. Run git pull. this will merge the automated commit into your local copy of the PR branch.
2. Continue working.

I do not want the automated commit

1. Format your code locally, then commit it.
2. Run git push --force to force push your branch. This will overwrite the automated commit on remote with your local one.
3. Continue working.

If you don't do this, your following commits will be based on the old commit, and cause MERGE CONFLICT.

The Glock 20 was recently added to the game, so make sure to include it as a valid tool and mod recipient

[Crystal9156]

It was just added 5 minutes ago I'm crying.

Updated to add the Glock 20

check if the other "auto switcher" for the AR guns is also in item groups (spawning somewhere) if so, add it into those lists alongside the AR one.

[Lamandus]

maybe change it to glockswitch? Maybe we have a samey thing later also with the letter G.

[Crystal9156]

Yeah I'll do this in case I make more switches/sears in the future and they don't all start with a single letter.

Lightning links and Autosears do not naturally spawn form what I see, I'll leave adding them and glock switches to the spawn pool for another PR if that's okay.

Definitely weird but not surprising that it doesn't spawn. I suppose I'll tinker with it in a followup in a bit then.

could this be checked again? the PR is opened from main branch, which makes it harder to pull updates

No one actually pays attention to what the checklist says... XD

it should be, in order to prevent nasty branch issues
