Were Killswitch Pistols stealth changed? Air reticle / accuracy is different

I need some people that use the Killswitch Pistols. I’ve used Killswitch pistols extensively since they released and still use them in Creative even though they’re vaulted. Since the start of this season, the in-air reticle doesn’t zoom in nearly as much and the accuracy feels noticeably worse than it used to. The weapon used to reward airborne accuracy much more consistently, but now it shoots as if I’m not even aiming in. Unfortunately, my whole play style is based around this gun now and I may have to move on.
