* a small note on the MP5-SD, it uses a ported barrel to keep all 9mm its fed at subsonic speeds= 115gr@approx 990fps...same for any 124,135, its fed. Which makes the same round loaded into a regular service 9mm pistol come out of the muzzle with more velocity & energy. Kind of a letdown for all of its cool factor and high cost of a select fire ,civilian transferable one(the cost of a really nice new car) or HK94 semi auto modified to SBR, and then to SD type suppressor(400.00 in tranfer tax alone) and folks seem to want 2,500.00
or so for the HK94 to begin with. Then when you have to shoot someone with it in a HD situation, it gets taken away from you and thrown around by property room folks until all the legal entanglements are over with.
Better off with a little .30M1 Carbine loaded with Corbon DPX ammo, or winchester HP and NOT tampering with the crime scene, Keeping ones mouth from making a case against them when the police arrives, and opting for an attourny before and during police questioning.....a shooting is far from over at the conclusion of the initial confrontation.( you can win the battle, and still lose the war.)
