Please answer these questions if you can.
Is the Taurus 92 the same thing as a 92fs? Do they take the same mags?
---no, and no. Pt92 is based off an older design of the Beretta. mags will not work because the mag latch are at different positions
Is the M9 and 92fs essentially the same pistol? Do they take the same mags?
---in a way yes, and yes. M9=military, 92FS=civilian. however u can buy M9's they might have some MINOR differences (sights, etc not sure myself). same mags
What is the highest capacity mag beretta makes for the M(9 or 92 fs)
---extended 20 rounds, sticks past the base tho
I recently heard that Beretta is putting some rails on the their pistols.
--- they have been putting rails on the vertec frame and 92G-SD (special duty)
Are the mags that are good for older m9s still good for the new M9s?
--- yes, M9A1 is basically the same as M9 but with rails
Are the mags for the 90-two the same as for the 92fs or m9?
--- think so, but since it is not out yet it is too soon to tell, tht or i don't personally know
What's the difference between the 90-two and the m9?
---90-two is not out yet, so there are a lot of differences, perhaps almost everything except barrel and mag. slide, frame,. etc are different.
