I have a Ruger 22 Mark III that I have been having problems with. I had other issues that I resolved by replacing the hammer bushing, loaded chamber indicator, and extractor with parts from Volquartsen.
The issue I have is failure to feed a round. This never happens on the first round. It probably happens 2 or 3 or 4 times per magazine. Racking the slide chambers the round.
I am using CCI Mini Mag plated cartridges so I don't think ammo is the issue (I have also tried Federal LRN).
I have also rounded the rear corner lips on some of the magazines to see if that would help but it is still getting FTF's.

"An ongoing Chinese hacking campaign known as Volt Typhoon has successfully gained access to numerous American companies in telecommunications, energy, water and other critical sectors, with 23 pipeline operators targeted, FBI Director Christopher Wray said"
"China is developing the "ability to physically wreak havoc on our critical infrastructure at a time of its choosing. Its plan is to land low blows against civilian infrastructure to try to induce panic."
I think this is actually just an elaborate Chinese marketing campaign to sell more radios and cheap survival gear.
