The only ones I’ve ever seen cause issues were on 329 Scandium 44 mags. They would lock themselves under heavy recoil.
I don’t own any guns with the lock but I’d get a “Plug” from the guy on the S&W forum if I did. Hey, tks, might be the same guy online too. https://www.originalprecision.com/lock-delete-kit.html
