I have read on some forums that rear stock from Beretta 391 interchanges with rear stock of Beretta 390 without any problems/modifications. If such is the case with rear stock then why Burris Speed Bead (as claimed by Burris tech) will not fit 390 if it fits 391?
Maybe some one here can enlighten me on this and explain why Burris Speed Bead, that is made for Beretta 391 will not fit 390, it goes between rear stock and receiver. Seems like it should fit since rear stock does.
If any one in this forum has had experience with this matter, I would appreciate their actual hands-on expert advice.
