9mm vs .45 acp Cinder Block Penetration Test
This video conducts a penetration test comparing 9mm and .45 ACP calibers against cinder blocks. The test uses a Beretta 92FS for 9mm and a Colt 1911 for .45 ACP, both with 5-inch barrels for consistency. The results indicate comparable penetration through a single cinder block layer for both calibers, with the .45 ACP projectile appearing to retain its integrity slightly better.
