Now I have to ask more about this. Can a Beretta 96D be transformed into a 92FS? Would the 92FS magazines fit and function in the 96D frame? How about going from double action only to traditional double action?
Yes any "D" variant (92 or 96) can be turned into an FS with the following, typically available, parts:
-"FS" slide with the safety wings vs the smooth "D" slide
-Non-bobbed "D" hammer
-Part # 31 (Hammer Release Lever)
-Part # 64 (Lever, Firing Pin Block)
from this Schematic (Schematic for Beretta® 92/96 FS / D / M & 22 Practice Kit - World's Largest Supplier of Firearm Accessories, Gun Parts and Gunsmithing Tools - BROWNELLS)
Like I said before, 92 and 96 mags will go into the 92/96 frame (Because the frame is the same for both calibers). The only thing that isn't compatible is the ammo itself. I highly recommend buying 92 mags for 9mm and 96 mags for .40 cal, and not try to load 9mm into the 96 mag. People have done it successfully but don't cheap out on safety.
The "D" variant is double action only. The "FS" is the traditional DA/SA...so this question is redundant. Yes you can convert.
I highly recommend checking out Beretta Forum - Powered by vBulletin for more information
Also, I have done this conversion and it is easy! All you need is a punch and the parts. If you want to do it and need help, let me know!
