I've heard that "need to defeat the involuntary second pull" explanation before, but I don't believe it holds true with all mechanical triggers. In fact, I think it's only true with a relative few of them (I believe the Boss system being one example.)

Example: I put snap caps in my SST Parker Repro. I pull once, trigger goes click, hammer falls; I pull a second time, trigger goes click again, second hammer falls. I know both hammers have tripped, because when I open the gun, both snap caps eject. How come I can get both hammers to drop with two voluntary pulls, if the system is supposedly designed to defeat an involuntary second pull? How would the gun know if my second pull is voluntary or involuntary? The Boss, as I understand it--don't believe I've ever dry fired a ST Boss--does indeed require 3 pulls to dry fire both barrels.

And while all 3 types of triggers have their devotees, one would do well to know the advantages and disadvantages of each. For example, if I'm only shooting targets, I won't worry much about the fact that some light loads might not reset an interia trigger. I'll find that out, and I simply won't use loads that don't reset the trigger. Likewise, not getting the gun mounted solidly probably isn't a big deal either. However, if I'm hunting, the mount can be an issue. Likewise, if I fire the first barrel with an interia trigger, break the gun open to reload, and a second bird flushes before I've reloaded the first barrel, I'm not going to get a shot off. I might get one off with a mechanical trigger, if I remember that I have to pull it twice. And if I'm used to double triggers, I can get a shot off if I remember to pull the back trigger. Advantages and disadvantages are different in the field (and perhaps more important, because you can always ask for another target--hard to just ask for another live bird to flush!) than on the target range.
