Heckler & Koch HK45 – ★★★ Handgun
Her damage buff is respectable for a 3* handgun, her tile layout… not so much. The X layout will typically make her excel in a 2SG2MG1HG setup. That setup is very niche and won't come up often. Outside of that, her buff tiles force her into a forward position as main or off tank. She's absolutely not suited for this with her poor HP and evade, and her buffs aren't good enough to really justify it mostly. If youre running and RF HG, you want Calico there usually.
Viable choice in a very specific scenario where you dont have enough handguns.
