Airsoft Arena talks about the pros and cons when choosing a pistol or an SMG as a compact weapon for airsoft... "It should not be a surprise to anyone who plays airsoft that the indoor environments are more populated with pistol builds. However, there is ALOT of misconception about how well pistol builds actually work or how well they actually perform. This is something that was demonstrated on the Airsoft Headquarters Channel when talking about the WE Galaxy, where the comparison was made between the tricked out HPA Tapped WE Galaxy vs a stock G&G PRK-9."
