Hi Andrei - Thanks for the comment and queries, here goes ...

1. The corners at the front of the frame. Been there since the 1970's, they obviously don't cause holster issues otherwise the American police and many specialist (NATO) armed forces wouldn't be using the 92FS as their standard side arm.

2. Correct, it's not the Picatinny rail system, please refer to 92FS compact with Accessory Rail at beretta.com - The basic idea is from there and makes perfectly good sense to me as an arrestor system to help prevent or possibly eliminate creep.

3. and 4. Are combined pretty much. As mentioned earlier I should have mentioned the concept parts and why... The frame grip is thinner to reduce the amount of weight at the rear of the pistol. This reduces the magazine to a one on top of the other round load, again reducing the weight at the back of the gun. The idea here is to reduce muzzle flip due to the excessive back end weight allowing the shooter to get back on target quicker. The reduced flip should improve accuracy and hence require less ammunition. The grips are supposed to be a silicon rubber with a gel like filling so if you hold the grip tightly it will effectively take on the shape of your hand, kind of like the memory foam pillows and mattresses. The thinner rail grip allows a greater volume to the front of the grips to work with, dropping off in density to the rear where less grip is required.

Not commented on by you but to help others better understand the design ...

The trigger guard is actually significantly fatter at the front and the bottom, this puts more weight forward and to the middle of the weapon, again in an attempt to reduce the muzzle flip. The silicon gel beads are there to provide greater friction but with comfort in mind, they will squish and help take to the contours of your finger prints and the natural imperfections in the skin that can change on a day to day basis depending on ambient temperature, stress and other environmental/biological factors.

There is another change to the safety mechanism whereas the safety catch and the cut out on the slide are identical on both sides of the weapon so a lefty can use it straight out the box without having to field strip the gun first in order to swap the parts round. This reduces manufacturing costs and should allow a faster rate of production as both sides of the slide can now be milled to the same shape.

Please keep in mind this is just a concept and has not been designed as a manufacturing ready design. It's idea based so even though it is not physically accurate, the ideology is sound and is open to anyone to play with it ... Just remember you saw it here first should you ever see it in production with someone else's name to it - lol
