The fundamentals of marksmanship are the same regardless of the type of pistol you are using. However, there may be slight differences in technique when shooting a revolver or semi-automatic pistol. For instance, the intrinsic differences between revolver and semi-automatic ergonomics will lead to some necessary adjustments in your grip. Obviously revolvers and semi-automatics do not reload the same way and feature entirely different controls aside from the trigger and hammer spur. One of the biggest adjustments that will change is the placement of the trigger finger on the trigger as discussed above. Shooting a double action revolver compared to most striker fired semi-automatics will necessitate significantly more leverage be acquired in order to manipulate it properly, particularly when shooting at a quick tempo. For seasoned shooters this is usually done automatically with little thought. New shooters will probably have to go through the revolutions a couple of times when switching from one to the other in order to maintain parity. That's okay, and this is generally not something to worry about, just something to be aware of.
