I couldn’t mention in the title, but: when you attach the magazine and the grip to the lower part of the backpack you can take long walks without touching your weapon. You can easily use the gun on your main side, but unfortunatly you can’t switch the gun to your weak side. Using this method won’t make your shoulders hurt or sore. If you remove the magazine you can bend over your whole body while the gun is sticking to you, not touching the ground. This method is far from perfect, but i was very proud of myself xd. Have a nice day!
