Of course, penetration is only part of the battle. Will your 9mm ammo actually expand after penetrating heavy clothing?
On this episode of Will It Expand, we aim to find out!
As we couldn’t find any heavily dressed bad guy volunteers, we resurrected the boots, stuffed them full of old shirts, and placed them in front of our high-fallutin’ wetpack bullet catcher setup. That gives us a reasonable approximation of a heavy coat or jacket and some lighter clothing layers. And with a lot less bad attitude than your typical street thug.
For the ‘short barrel’ part of the equation, we used a Glock 26 Gen IV which is in for review. A great little gun that packs 10+1 rounds of 9mm and features a 3.4” barrel – perfect for our carry gun test. Shorter barrel, a little less velocity, and a good bit more stress on hollow point performance through barriers.
On the ammo side, we’re trying three different 9mm loads:
Once again enduring the strange looks at the range – “Why on earth do those idiots keep shooting cowboy boots at the range dear?” – we persevered and shot the boots, dug bullets our of wet and nasty wetpack, and brought you the results. Just as a side note, it’s amazing how much wet junk mail resembles used diapers.
|The CorBon loads all expanded beautifully.With one we did have jacket / core separation, but overall they made cute little mushroom shapes.If anything, the CorBon loads expanded a tad too much and penetration was about 50% less than that of the other two loads.Chalk this up to a lighter bullet than the Georgia Arms Gold Dot and bigger expansion than the Critical Defense projectile of the same weight.|
|The Georgia Arms Speer Bonded Unicore loads were solid performers through our tough, winter attired, evil d00d simulation.Out of seven rounds fired, five expanded perfectly and demonstrated excellent penetration. Two projectiles partially expanded.|
|All four Hornady Critical Defense projectiles had excellent penetration.Two expanded perfectly, the third had perfectly adequate, but less photogenic expansion, and the fourth had some deformity and partial expansion.|
We were somewhat surprised at the good performance turned in by all three loads out of a shorter barrel concealed carry gun. We’re waiting on a backorder of the new Hornady Critical Duty 9mm load, which is a bit heavier, and will test that against a heavier CorBon 9mm JHP load. Should be interesting.
