So i go into a local pawn shop to look at a Glock 20 they hand me the gun and i ask if i can take it apart. they say sure so i take it apart and as i do the lady running the place tells me not to dry fire the guns . i explain i have to dry fire it to take it apart and you can dry fire Glocks without hurting them, she tells me not here and points to a small sign that says do not dry fire the guns . so i put it back together and leave. This is just crazy to me i understand if its an older model gun revolver or something but to tell me i can take it apart but i cant dry fire it how do i do this , i think if you want to work in a gun store you should at least know the basics i wont name the store as not to start bad blood but that's just silly ok end of rant
