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.

APC9 Pro SD vs MP5(8.9in), MP5K(5.8in), MPX-K(4.5in), and P365X + PMM comp(3.1in) APC vs MP5 - 300fps loss APC vs MP5K - 260fps loss APC vs MPX-K - 197fps loss APC vs P365 + PMM comp - 119fps loss Above are averages of combo of 115, 124, 147s of cheap remans, factory std and +P ammo. The SD system seems to do more work on the +P rounds. That being said, the +P 124 HSTs seem to slow down the velocities to what you'd get out of a regular 124 HST in a P365 3.1in barrel (1009 to 1019fps) All measured with a Garmin Xero C1 Pro on 22 June 2024, 368ft elevation, 94F, 29.95inHg, 42% humidity, ~8mph wind coming from around 4o'clock from position.

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 🫡
