I worked for an armored car company some years ago, and the company issued Ruger stainless steel Speed-six's. I was off the road for a while and working the midnight shift securing our facility, and due to my ability with firearms I was tasked with cleaning and checking the pistols, something which had not been done in years. I spent a month using a soldering iron to peel lead from around the forcing cones and sanding rust off the blue-steel grip screws, but I digress.
On fine day my relief called off and I had to stay late and help the trucks get on the road. I'm sitting in the tower overlooking the truck bay and I notice one of the guards loading his revolver before getting in the truck and leaving. Another guy is pushing a cart loaded with cash and coin past him when he turns and collides with the cart, and I watch the pistol fly from his hand and sail majestically into the traffic lane, landing just in front of the duel rear tires of a large MOVING armored car.
The tires roll over the pistol and then a silvery blur shoots out from under the tires and CRACK! The gun slams into the back wall of the bay. A hundred heads pop out of bays and vehicles, people have their guns out looking for the source of what many believed was a gunshot. Skip over several minutes of cursing, recriminations and laughter, to the head of security handing me the pistol to examine. The front sight was a little mashed, and the entire top-strap and barrel are stippled and coated with the dust of one shattered cinder block and the cylinder has a big scrape mark. I push the button and the cylinder opens to reveal six perfect primers, although a chunk of one of the grip panels pops of in my hand at this point. I proceed to give the weapon a function check and everything works! The cylinder locks and unlocks, the transfer bar goes up and down as does the hammer, the chambers appear to line up, everything. Needless to say I told the boss that it needed a gunsmith inspection before it went out on the street, but the dang thing worked.
Now you know why Ruger builds the only revolver I own.
