Pistol Amp adds to the base damage like Hornet Strike does.
 * New base damage = base damage * (1 + Hornet strike % + Pistol Amp %)

So with a maxed Hornet Strike, it will only grant you a 8.4% damage increase, due to Hornet Strike's already very high damage increase. Thus, Corrosive Projection will still yield you higher damage output against armored targets and Shield Disruption will often be more useful than this against shielded enemies.

Sorry Pistol Amp :/
