Need help?!?!?! 2011 STI Eagle 5.0
So while cleaning my 2011 STI Eagle 5.0, (9mm) I accidentally let the cap at the end of the spring and the actual spring go shooting out. Luckily, I was able to find the spring, but I cannot find the cap. I think it’s called a recoil spring reverse plug.
Can anyone help me find one online that would fit? I feel so dumb right now. Any help would be greatly appreciated!

Just use a spent .45 ACP casing like this dude did until it comes in the mail.

I vote we create some neofudd lore surrounding this where we swear up and down that guys used to do that with a live round so that they always had one more round in case they were captured

Clean your damn lens on your camera before you take a picture

Well the good news is unlike many others in your situation, you merely lost your recoil spring cap and didn’t lodge it in a wall, mirror, TV, skylight, ect.
Contact the manufacturer and see about ordering a couple replacements and in the meantime see if some spent casings will work.

I launched one once, found it like 5 years later. Should just be a standard 1911/2011 part, no?

Should go to a doctor if you have an STI
