Thanks WildBill.

This is one reason that I stay with Colt revolvers. I happen to like them better, too.Excaliber wrote:In my agency we taught our folks to load and rotate the cylinder in the opposite direction that the cylinder rotated when the trigger was pulled. On the S&W guns we used, we loaded clockwise for the counterclockwise cylinder rotation. The reason for doing this was that as you placed rounds into the chamber, if you had to get back into the fight before a full reload, you would have live rounds come up right away.
I can confirm Steve's experience. As our department's training commander, I developed and ran some fairly challenging tactical scenarios. The first year, in almost every class, someone kept his finger in the triggerguard and "fired" when he shouldn't have when surprised by a panicked "victim", "homeowner" or "unarmed suspect". Our observers immediately challenged the "shooter" each time to defend his use of deadly force. In each case, he or she stated the shot was unintentional and they didn't know why they had fired. We explained that it was triggered by the involuntary hand clench phenomenon that accompanies the startle response. Hearing about this in the classroom and seeing it actually happen are two very different things. It was a sobering experience for all present, and validated our heavy emphasis on keeping the finger out of the triggerguard until the decision has been made to fire. It left a strong impression that carried over into the street. During my time as training commander in a department of 200 officers, we had no negligent discharges and no unjustified shootings.srothstein wrote:As an aside, I don't truly believe that double action will prevent accidental shootings as much as some people think. During one of our training scenarios, we were searching a building for a burglary suspect. We were taught to search with the revolver in what we called the third eye position (against the stomach and facing the muzzle at whatever we were looking at). The logic of this position is that the only way we would know [abbreviated profanity deleted] the threat would be watching it come at us and this way the weapon is already pointed at the threat. Anyway, it is good that we take safety seriously and we were searched and checked multiple times for empty weapons and no ammo (on cops or cadets) in the training area. As I came around a corner, the detective playing the suspect steps out at me, throws his arms in the air, and says "Don't shoot, I give up". We both heard the click of the hammer falling (and it was double action that time). Afterwords, he told me he never failed to draw fire by doing that. And I have never put my finger on the trigger until I was ready to fire since then either. Better to learn these lessons in training than in real life.
My training started similar to Steve's. I just remembered another part of my training that was very common for target shooting and hunting - loading five rounds in a six cylinder revolver. This was taught to prevent an AD if the gun were dropped. Loading five rounds, one-at-a-time, and then indexing the cylinder increased your reload time and reduced your capacity. Obviously, using a speed loader eliminates this problem.srothstein wrote:What happened is that my father started me shooting when I was 8 years old, with an old S&W revolver. Form then on, until I went to the SAPD academy when I was 30, I always fired single action with my revolvers. I think it is the most accurate way to shoot for target shooting.
The 5 loaded / 1 empty procedure was adopted to prevent ND's with traditional single action revolvers, which had no mechanism to prevent the firing pin from striking the primer if dropped on the hammer. I don't know exactly what guns Steve was working with, but 5 loaded / 1 empty is unnecessary with virtually all modern double action revolvers, which have transfer bars, hammer blocks, or other devices that only allow the gun to fire when the trigger is fully to the rear, and which prevent discharge if dropped.WildBill wrote:My training started similar to Steve's.

Steve was talking about shooting "an old S&W" around the time frame of 1964 when he first started shooting revolvers. Even though transfer bars and hammer blocks later became more common, many people still only load five rounds. Five is also a convenient number of cartridges to load for target shooting. The point is, whether neccesary or not, old habits sometimes die hard.Excaliber wrote:The 5 loaded / 1 empty procedure was adopted to prevent ND's with traditional single action revolvers, which had no mechanism to prevent the firing pin from striking the primer if dropped on the hammer.

True enough, which is why it's important to train like you want to fight. What you've done the most in training is what you're most likely to default to under stress, as Steve's experience confirms. If what you do most is not optimal for survival, chances are real good you'll do it anyway in a fight because fast analytical thinking is one of the first abilities you lose when the adrenaline gets dumped into the system.WildBill wrote:Steve was talking about shooting "an old S&W" around the time frame of 1964 when he first started shooting revolvers.
