I am a new shooter, well new at pistols. I used to shoot clays. I have a question Double Action/ Single Action triggers. What exactly does this mean. It seems most of the guns i am looking at are da/sa. I really want a sig p226 but for right now it is just a little outta the price range. I like the Beretta Px4 Storm, i don't want a glock. Any help on the subject would be appreciated. This gun will for the most part not be for cc.
