Today we are taking a look at the actual velocities out of a SD system from B&T. This is the GHM9-SD that we've featured in a few videos and shorts at this point. We are going to run a baseline comparison to the MP5 with the B&T RBS SQD suppressor, and provide some quality sound comparisons between these systems incorporating different ammos. Ammos used for this video include 115gr, 124gr, 147gr, and 150gr

Today's video is also brought in part by Die Free Co. You can grab you some kung fu grip in all kinds of colors here:

    What do you like shooting more ghm9sd or maxim sd. If you could only choose one to own.

    What does this porting do for an self defense gun though? If it makes 9mm even more anemic I wonder how it fares against a target with a leather or carhartt jacket, or heavy winter clothing.

    I’m a suppressor nerd and I don’t mind the 30 minute videos. Good job as always 🫡
