@Mark, Yes, I carry when I ride.
@Ahlir, OK, the whole story. . . The Rodney King riots had started in Los Angeles on a Wednesday, this was 11:30 on a Friday night and I was riding my bicycle home through Wilkinsburg. One might think that was an inherently bad idea but I rode through Wilkinsburg every day for years without any particular issues and it was essentially the only route home so I had little choice. Besides, the Pittsburgh Media and authorities were assuring everyone continously that "those things" weren't happening here in Pittsburgh.
At South Avenue and Pennwood, I came upon a pair of angry youths, armed with a baseball bat. At the time, I carried a 9mm pistol in a "fanny pack" holster. I normally ride with it to the back and I moved it around to the front. They saw me and I attempted to flee. Given the geometry of the attack I realized that I was not going to be able to out maneuver them on the bike so I attempted to get off the bike so that I could run. Unfortunately, that did not go smoothly and I fell in a tangle of bicycle just where the railroad tracks cross South.
I got up and started running. I could hear their sneakers slapping on the concrete just behind me and realized that I could not outrun them. I drew my pistol and turned.
The one attacker, the one without the baseball bat, was right behind me and I literally had the drawn pistol inches from his face. I ordered him to "Back off."
In that moment, I saw his entire attitude change. He ceased attacking me and just stood there. I again ordered him to back off, and he complied. His partner, with the baseball bat, attempted to flank me and I presented the pistol in his direction to keep him back.
It was about this time that I realized that, in the fall, I had lacerated the index finger and thumb of my right hand. There was blood all over the gun, my shirt, all through the holster.
They backed off and started taunting me, like yappy wolves. If they were going to give me some distance, I was going to attempt to salvage my bike. I moved to the busway entrance and there was someone in a car there that I yelled to them to get help.
"Don't watch. Please, call the police"
That driver just stared but eventually drove off when I got to the other side of the vehicle and my assailants attempted to use the car to flank me again. I ditched the bike and backed up quickly. Within sight of the Wilkinsburg police station, they stole my bike. (They didn't get far because I had screwed it up in the fall.)
I went to the fire station and pounded on the door to get someone. After a fireman stuck his head out the window I realized that I still had the pistol in my hand and thought it would be best to put it away. It was then that I saw that the pistol was in the half-cock position. I had been literally half way through the double action trigger pull when my assailant backed off. A near thing.
The cop who took my statement said I should have shot him. The EMT who bandaged my hand said I should have shot him. I spent the next few hours in the hospital waiting room wondering if I was going to need stitched and watching continuous replays of Reginald Denny getting the shit kicked out of him.
I have no doubt that if I were armed with anything less than a firearm, a taser (which weren't available to the public back then), a stun gun, pepper spray, my fists, I would have been unable to defend myself sufficiently that they would have beaten me until they grew tired of beating me. I also know that if my attacker had done anything other than what he did when I had the gun in his face, it would have taken 4 pounds of pressure and about two-tenths of a second to send a 115grain hollow point through the bridge of his nose at 1100 feet per second and he would have died instantly. As it turned out, we all got to go home that night.
I bristle when people tell me that I should not carry a gun to defend myself because I know that without it I would be dead or, if I was really lucky, merely permanently disabled.
