I don't see it. If the gun is unloaded, he can't fucking accidentally shoot the someone or himself. So keeping his finger away from the trigger isn't going to matter.
If he was handling it that way while loaded, then I totally agree.
so many people get shot w/ "unloaded" every year because idiots don't respect what a projectile traveling 1000fps+ can do when coming in contact w/ a human being. you have to just know not to put your finger on the trigger unless you intend to use it, plain and simple - learn it, live it and it becomes muscle memory - at this point w/ the ops first gun, he is off to a bad start because when you pick up a firearm your finger needs to not go into the trigger area automatically. it takes the way of accidents that shouldn't have happend when somebody fucks up. gun ownership is a responsibility and in the pics the op has shown total lack of respect for the firearm.
if you are going to dry fire, you clear it, check again, then when you do dry fire it is in a safe direction, not just pointing anywhere. w/ gun ownership and safety you have to be right 100% of the time, so you always treat the gun as loaded regardless of the state you know it to be in last - you still check it again.
