The MP40 was a stepping stone, one that came along at a very troubled time in world history. But as with all weapons, the gun has no agenda or conscience, it is the implement of its user’s intent for good or bad. The MP40 has existed long enough to have played its part on both sides of that line. As a CO2 model, it is more of a tribute to technology and firearms evolution. The MP40, like any great and enduring firearms design that has been recreated as a CO2 model today, is a part of history that we can hold in our hands.
