I don’t know of any others that are truly leftist. The best I could find is this list of makers that are at best apolitical.

Otherwise, I’d opt for EU gun makers, or a used one from a left leaning gun shop, if you can find one.

They would be outgunned against anyone with a rifle, or even a semi pistol, unless they have speed loaders.

I assume you’re suggesting they use it like a liberator pistol, like the French resistance in WWII. But bear in mind that any of those resistance members would’ve preferred to have a more capable weapon from the outset, and having to dangerously acquire one was an option of necessity, not preference.

Better to equip at OP’d leisure and choose something that’s ideal to their needs while they can easily and cheaply.

A PDW type thing is a good idea. A ruger LC Charger could work, either with a cheek hold, or a brace.

I don’t think a slow long-arm is a good suggestion for this application. An AR-15 in .223 is the best all-rounder that will work out to ranges that most people will likely use them at.

You didn’t mention your budget, so I’ll first suggest a WWSD rifle, which is a particularly light weight AR-15. They also make a cost reduced version that’s half the cost while only being a little heavier at 5.4lbs.

I suggest these for two reasons,

1. They’re genuinely excellent firearms. Well constructed, reliable, with easily replaceable commonly available parts.
2. KE Arms is one of the few leftist gun makers in the country, who fully support LGBTQ Gun ownership. One of the people who helped design the WWSD rifle is an Anarchist who makes excellent videos on youtube (InRangeTV).

If you have a lower budget, the best option is a simple PSA AR-15. They also make a ‘pistol’ version that’s about the same weight as the KE Arms versions, but with a shorter barrel (which would be much louder than the longer barrels, something to keep in mind).

For information on how to use them, I’d recommend taking a look at Tacticool Girlfriend’s videos, especially her series for beginners.

Also, don’t neglect getting medical equipment (a small IFAK) and learning how to use them!

If you ever want to opt for armor, I’d suggest either a used level II or Level III Kevlar vest and a MICH helmet from eBay.

If you want rifle protection, consider Redstar Defense, a leftist armor maker that makes quite excellent ceramic armor plates for a very afford able price.

Whatever you go with, try to link up with like minded people and become organized in your community. Here’s a solid guide on how to do that.
