The AFF Universe Wiki also has an article on this topic: EVP 'Eagle' Infantry Weapon

The AIA exclusive pistol, nicknamed 'Eagle'.

Compared to AFF's other pistols (the ULA Corps-Miyaki UDP and the neutral Sikfrit Model 54), the EVP lies somewhere in the middle.

In a direct comparison with the UDP: it's rate of fire and magazine size is lower (and it lacks a 2 burst-fire mode), but it's damage per shot is almost double.

It's main advantage over the UDP is it's reload time of 2.10s: even if you need to reload mid-fight, you won't be waiting for long.
