I always carry on after hours service calls and I normally don't carry this pistol much anymore but I had it at the range earlier. It's what I had on me so it's what I took with me when the call came in. Well this is a little embarrassing to say but it's a testament to HK's durability. I was on a after hours service call to work on one of or trucks. I don't know how this happened but my USP 45 compact worked it's way out of it's holster into the mud puddle where I was working. After the job was done I gathered everything up and it wasn't until I was back in the service truck that I realized that my pistol wasn't in it's holster. My heart went into my throat! I looked around and didn't see it. The last place that I looked was in the mud puddle right next where I was laying. Right where the wheels of the 18 wheeler just drove through! Yes, that's right, A 80,000 pound big rig just ran over my fully loaded USP .45 compact! Granted, it drove it into the mud about 5 inches so it wasn't like it was on solid ground or pavement but still! I nearly S*^# myself when I pulled my gun from the mud! I wasn't expecting it to survive. I got back into the truck, dropped the mag and wiped the pistol off. I racked the slide and behold, it cycled fine. Good so far, When I go back home I field stripped the gun. I cleaned and inspected everything. All was good except for a small spot on the frame where it looks like a rock or something hard scratched it a little. (I seriously need to get a digital camera that works!) Anyhow, I took a drive over to a place that I could shoot this time of morning and not wake anyone up. 100 rounds fired and 0 malfunctions! The moral of this story? Avoid opened top holsters while on service calls in the future! HK makes one HELL of a durable firearm! I feel like a ass that this happened! :embarassed: I'm sure that other makes of firearms would have survived also but I hope to not have to test them in the same way!
