Received four boxes of the new Critical Duty 9mm 135gr +P round from Midway USA ($22.99/box - 20/box). Fed fine through my G19. I "test" my carry ammo by shooting into 4 gallon jugs of distilled water at 15 feet from first jug. The Critical Duty round went through all 4 jugs and I couldn't find the slug. This is the only defensive round that I've ever shot through this "test" that went through all 4 jugs. tnoutdoors9 who puts his tests on youtube tested this round through gel and got a 16.75" penetration (4 layers of denim) with 0.52" expansion. Little too much penetration and expansion for my tastes. Conclusion: I'm staying with my Speer Gold Dot 124gr +P round (13.5" penetration with 0.75" expansion).
