Make immersive reload immersive. Instead of "Press button to start reload" it should be similar to what you did in breachers but with addition. There is holster on left hip where mags are holstered. You able to take mag matching current gun anytime, not only with empty magwell. Box mags can be interacted anytyme, not only after pressing button. There can be additional button lock but for hand holding mag (if its gun without mag release). E.g. when you detach AK mag, you grab it with offhand, press B/Y, and move your hand out (or just take a new mag and bump an old one with it). For guns with mag release there can be additional way, the same that your Glock 17 has. Also there should be slide lock and release, for guns that actually have it. To save ammo you need to grab not empty mag from your gun and holster it back. Mag palming also would be a good option.
