Watched "Magnum Force" with Clint Eastwood and David Soul last night on AMC. In the scene where Eastwood and Soul are competing in the combat course for the championship, the interresting part was the revolver reloads. Eastwood, naturally, is using the M29, with Soul using a Colt Python.
The reload method used by both was to leave the pistol in the shooting hand (SH) and emptying, reloading and closing cylinder with the non-shooting hand (NSH). They opened the cylinder with SH, emptied cylinder with NSH, got a speed loader from their belt or pocket, with NSH, reloaded cylinder, dropped speed loader and closed cylinder with NSH. Areas of loss of time, emptying cylinder, dropping hand to get speed load, go back up to cylinder and load. Other area is closing cylinder with NSH and getting back to shooting stance. Tombogan stated that he uses this method but picks up speed loader before emptying cylinder and has it ready to reload, saves time.
With the method of transferring pistol to NSH when pistol is reloaded NSH which is holding pistol by cylinder with thumb in position to close cylinder as soon as cylinder is loaded. No shifting or positioning of hand. Then the pisol is transferred to SH with NSH in close proximity to affect a reacquiring of shooting hold. Saves time, extremely important.
I realize that Hollywood shooting and real shooting are totally different but the cylinder reloading techniques are basically the same.
