Testimonial by Officer Stroik:
I’m writing you to share an experience I had earlier this year. I’m an LEO in the upper Midwest. I have your extenders on my G21 to give me more rounds in the event I ever needed them; that event happened in the middle of January. I was assisting another agency ATL’ing a vehicle theft suspect. As I rounded a corner I was met with an armed suspect with an outstretched arm and gun pointed directly at me. A gun fight ensued with both sides firing multiple rounds. The suspect was pronounced dead at the scene, no LEO’s were injured. If I didn’t have those extenders I would have run out of ammo during this incident. My mags and weapon were taken as evidence during the investigation. I called Henning to see if they had any old extenders laying around the shop and explained I would send them back after I got my mags back. Henning himself called me back; I explained what happened and my request. He told me he would send me brand new extenders for free. The amount of compassion and empathy he showed was simply incredible. I cannot say enough good things about this company and their customer service. Thank you, Henning Group.
Stay in the fight, stay safe.
