{Request} Underbarrel Weapons W/ Non Standard Magazines

[jak2921]

It Pains Me That I Cannot Equip An Under-barrel Shotgun With A Dual Magazine On Any Of The Weapons Despite Most Magazines Not Interfering With The Function Of The Under-barrel Weapon Or Vice Versa.

If Someone Better Versed IN MGSV Modding Than Me Could Make Or Explain How To Change This Either By Modifying The Magazines Or Under-barrel Weapons Them Selves I Would Be Exceptionally Grateful.
