Has anyone else ever heard of this? Or am I just out of the loop... Apparently Tokyo Marui has found a way to create a spring pistol that is also semi-automatic. So far there is only a G26 (in various colors) and a PPK (also in various colors). They seem like quite a nifty novelty and quite inexpensive at around 20 bucks I believe. Only downside really is they max out at around 200fps, but an accurate 200fps. Here's a few video's of KhanSeb shooting them:
