I was having a discussion with a friend about subsonic 300 blackout and I was of the opinion that it was basically the same as a 45ACP and I didn’t like any of the ammo that was on the market for self defense.

So I decided I hadn’t done a JCN Ballistic test in a while...

My criticism of the 194gr Maximum Expansion subsonic Underwood round was that it was only good for gel blocks and I wasn’t convinced it would be any good with hard barriers. I also thought it would essentially perform the same as a 45ACP.

So I brought out my 45ACP Kriss Vector and my SBR 300 blk AR to test.

I set up a test wanting the 300 blk to fail. I put 3” of gel and then 2 pieces of 22ga steel at a 45 degree angle, then more gel.

So I tested and...

The Underwood round fully expanded in 3” gel and punched through the steel. Then went an additional 9.5” in gel past that!

The 45 didn’t make it past the steel.

Hit the “like” button if you like these tests. It’s been a while since I’ve done any.

The .45 is a relic caliber better suited for a bygone era. If it were not for the nostalgia associated with the 1911 it would be long gone.

I am sure that the USMC MEUSOC will be interested in hearing from you so that they can correct their grave oversight.

The USMC is still using the M45A1 CQBP, a modified M1911A1 in .45 ACP (NSN 1005-01-370-7353), which began service with the MEUSOC Recon Battalions and Security and Emergency Services Battalions in 1985 and remains in service to this day.

So does the 9mm. Lol!
