The M9A1, and 92A1 are, in my opine, off spins of the short lived Vertec.
The Vertec is essentially that handgun, with a flush fitting barrel, and straighter grip. The Vertec, like the 92A1, offers the user the opportunity to replace the front sight. It employs the polymer trigger, and safety switch, and I believe that Beretta had offered a short trigger retro-fit, for women and others with smaller hands. Other than that, it is EXACTLY the same as the m9/92 A1 series.
I've owned a Vertec since they were intro'd, and have ZERO issues in it's life with me. Thousands of rounds!
Awesome video fella, very informative review.
Here's a web pic of the Vertec, notice the grip angle of the Vertec is close to, but not the same as a 1911.
Still uses the 92/M9 series mags tho.
