The bolt release is an M3 screw. The factory is too short. Find an M3x6mm button head screw and buy 5 or 6. My True Value had them at about 30 cents each. Use LocTite Small Screw thread locker.

Thanks for the help guys, running to Ace Hardware today after work to find a screw.
Another question, I have 21" 1301 with a +4 and added a +1 to that. I am now looking at chokes for it. Noticed that most of them are either flush, extended + 3/4'' and a 2''. Is there a difference in performance in going with a 2'' instead of a 3/4". Only reason why I'm leaning with the 2" is so they magazine tube wont look so long.
FYI, Beretta is running a 25% off sitewide at their online store.
