I'd replace the pins and the retaining plate at the same time..both are cheep enough not to worry about

I remember some where was selling longer axis pins.
Using a longer pin and the plate would keep it from walking out.

I had that problem on a AR also but for those they sell anti walk pins with cap screws on both sides... To bad they don't have those for AK,s... Again you could use E-Clips and install two in each slot ( gets them in there tight) till you get new pins and a new plate...Just saying and don't send me mad posts cuz I recommending clips it's a temp fix.... so you can go on shooting..... but only remember install two in each slot it takes some effort and its tight but they have never backed off or fallen out on my guns....I don't like the wire retainers but on full autos that is the only way to lock the pins since they don't make plates for those... I don't use clips any more since I learned to modify my Akbuilder plates for my left hand safety guns but I used them for years on these two Ak.s and my Galili and never had one fall out....I still keep them in my gun bag just incase..

Once again, thanks for th word on the extended length pin, it solved the problem!
