Yes I notified Weigand about this when it happened to mine.

What I got was a "we will replace the mount under warranty this one time only....", yet the new mount showed up with sold steel pins.

I think they know it is a problem, but probably don't get enough returns for it to be "worth their while" to fix the issue.

I really wish they would just extend the mount back to the rear sight and put a recoil lug there like they do on the 454 and 480 SRH mounts. That would solve the problem for sure.
