Casually, yes. He was definitely casual about the presence of a gun but he was kind of used to them being around. The bouncers at the club usually at least arrived armed though they generally disarmed once on the clock. And hell, man, everyone in this part of the fuckin' state was armed.
And... okay, maybe a bit of kink but mostly for the handcuffs. Shae's laughter made Mirza laugh not at all offended by it. It was a very giggly sort of situation. He bit his bottom lip lightly, watching Shae shift the jacket around to expose the gun neatly in its holster.
Mirza was going to take advantage of how open that invitation was and instead of reaching for the gun, he hooked his thumb into the waist of Shae's pants rather boldly, arching an eyebrow, "Just how... loaded are you?" He stuck the tip of his tongue out between his teeth at Shae, grinning broadly. Oh he was tired so he was feeling goofy.
