Simple and really short suggestion.
It could be in appearence menu or if you click t to chose how you can hold(i know if you press t to change attachments but would be easy to use)
well i just give one enxample and fotage about that feature:
as you see mine thoughts on one hold kind
its just grab closer to magazine and benefits you with:
10% quicker reload and 8% minimalized recoil + cool stance
If you have mounted grip to gun you shoud change stance to normal (where was before non-dominant hand on handguard)
there could be more or few of them allows for more customizanation for our characters
Note: this shown stance only work for two-handed guns such as: Bolt action, Assault rifles, Submachine guns, ect.
