I have made some life-sized replicas of some pretty cool weapons using LEGO. They're big enough to fit in your hand, and they are pretty neat.
About this creation
9MM Pistol from Half-Life 2
I tried to create the best-looking replica of the 9MM pistol from the famous Half-Life 2 game series. I tried to fit the look of the original pistol from the game as best I could. The front is somewhat rounded, and there are two yellow lights on the back (just like in the actual game). Below are some pictures of me holding it.
Sub-Machine Gun (SMG) from Half-Life 2 » I will be taking pictures of this (if I still have it) and posting them soon.
Assault Rifle from Halo
For the assault rifle, I wanted to make it look as close to the original architecture from the actual game as I could. As you can see, a lot of special pieces were used in the creation of this replica. It matches the body of the assault rifle from Halo quite well, if I do say so myself. It is sturdy enough to be held in one hand without holding the front with your other hand. It is even equipped with a small flashlight that is hidden in the lower front area of the replica. There is a small opening under that area of the replica where the flashlight can be switched on and off. It is actually pretty neat. I can be held in a real-life manor, which I think is quite cool. Below are some pictures of it, and I plan to post more later to show off more of its design.
I tried to increase the brightness of the replica in this picture using Photoshop (as I did with all the other pictures), but it turned out looking a little like tape was placed on this photo. Sorry about that.
