The Spike's Tactical STG9 Pistol was assembled using a Spike's Billet (Gen II) Receiver Set that is compatible with Glock 9mm magazines along with numerous upgraded parts.  The receiver set has pockets that have been machined in many areas to reduce weight.  The lower receiver design was engineered to shave the weight and increase strength exactly where we wanted it.  All edges and surfaces have been 3D chamfered to reduce snagging. Enhanced pivot and take down pins which were designed around the lower receiver for a unique integrated look. These are made of steel. 3D machined logo pictogram is the reverse look of a traditional lower receiver. Large flared magazine well.  Spike's also decided to take off the door, forward assist, and shell deflector, to keep the profile as slim as possible.
