Introduction: MMP-1

This is my 15th K'nex gun I'ble and 30th I'ble altogether. This is my MMP-1 (Masterdude Machine Pistol model 1). It does not use my semi-auto mechanism but uses one based off of my MAR-4 mech.

    nice!

    It would improve performance greatly if the pin wasn't directly attached to the slide, and likely also improve firing rate.

    I know. Maybe in my next guns with firing pins I'll try to make them not attached to the slide. As for the firing rate, if you want fast, then you want my other guns.

    What exactly gives it the mM-p rating?
    The machine bit, I do not understand.
    And, also, stay around with the semi auto! Please???

    The "M" (Machine) is just because of the resemblence to Machine Pistols and kind of because it is created for fast firing because of the large(-ish) mag and the slide which should make the firing speed relatively fast.

    Also I will continue to make the semi-auto's but currently I am unable to post more guns so for a while (until summer ends) I will not post any semi-auto's.

    Your gun would be better if the pin wasn't so heavy, and if it was longer. Maybe make the barrel longer too.
