Ammo Quest 9mm: MagTech Guardian Gold and First Defense test


Subscribe to Channel

This is Thirty-Seventh test in a series of a quest to find the overall best defensive ammunition for modern 9mm pocket pistols (such as the Sig Sauer P938, Taurus PT709, the Ruger LC9, Kahr CM9, Beretta Nano, Kel-Tec PF9 or S&W Shield or any other popular 9mm pistol using a barrel length of approximately 3"). The test pistol for this review was a Sig P938.

In this installment, I am testing the MagTech First Defense 92.6-grain solid copper hollowpoint, and the MagTech Guardian Gold 115-grain +P JHP, and the MagTech Guardian Gold 124-grain JHP.

I am chronographing the rounds as well as firing multiple rounds per block so that we get a more statistically relevant result, rather than the typical ammo test where only one round is fired. Ammo can behave a bit unpredictably, and the results of any one bullet are not necessarily representative of how the ammunition performs overall.

The purpose of this testing is to find which rounds of ammo perform well enough from a short 3" barrel that they can reliably deliver the penetration (with expansion) that has been documented and proven necessary in order for the bullet to be able to reach the vital organs of an attacker and deliver an incapacitating hit.
