I have two 92A1s, two M9A1s, and I previously owned two 90-Twos. I tried to like the 90-Two, but the grip really sucks. I ended up selling the 90-Two each time. I couldn't like the gun because of the grip.
There are NO aftermarket grips, and the factory grip is just too slippery. That's the biggest complaint ya see over and over about the 90-Two.
Also, while the 1 piece polymer grip is replaceable with a "thin" grip to make it look like a Beretta Vertec grip - good luck on actually finding the "thin" grip. There are guys at the Beretta Forum who have looked for months. No one seems to have them in stock, and they have been out of stock for months at most places, if not longer.
I'd suggest getting the 92A1. It has the updated features of the 90-Two, but it has the regular 92FS grip. So, ANY 92 grips will fit the gun. Also, the 92A1 comes with THREE 17 round mags.
Be aware that even if you buy a regular 92FS, though - you can use 17 round mags in any Beretta 92 9mm variant. And, you can use 15 round mags in the 90-Two or 92A1.
