well my Glock 17C is in the bedstand, and my Dragunov SVD is on the wall, and my Nihontou are on the other wall, i have a Beretta 950 Jetfire in the safe along with a Beretta 92SB and a Colt 1911 Series 70. The gun cabinet in the corner has a Remington 700 LTR, a Mauser K98k, a M1 Garand and hopefully in the next few months ill be putting a Accuracy International AE in .308 in there too.
SO i guess its more like whats the MOST deadly, but then, i guess they're all pretty deadly. Inside my room, the Glock is most deadly though, its what im most well trained on, and its within easy reach and extremely useable within the room. So ill go with my Glock.
