The L22 most likely fires a FMJ bullet, in accordance with several conventions banning the use of expanding bullets in warfare. Which means the kinetic energy of the round isn't fully utilised.
The Beretta 92FS most likely uses 9mm JHP, and would expand when impacting the target.
So i guess that looks legit.
Well, from one firearm enthusiast to another...
A 5.56mm round with a 55~67 gr. FMJ bullet exiting the 17.4" barrel of the L22 at a likely 2400+ fps would dwarf ANY 9mm pistol round. As I've pointed out in the past, (to the apparent consternation of some), the in-game Bullpup is ejecting
pistol cases, does, at best, pistol-like damage, and should have been depicted all-along as a submachinegun using, of course, pistol-class ammunition. And, how likely would it be to find non-FMJ 9mm ammunition in handgun-unfriendly England?
Again, I'm not advocating for, nor expecting, the depiction of the weapon to change. In my mind, it IS a subbie. But if I woke up and found that it was suddenly transformed into a MP5 or some-such, with no changes in sights, stats or balance, I'd sure welcome the event.
