All of mine are hammer fired but mostly because all of my center fire pistols are hammer fired (I just like hammers better). Although all of mine are not the same manufacturer, all of the guns I use for SD/HD operate similarly. In other words, the 5905 operates for the most part like the Beretta and the Stoeger do. But again, it's more because I just prefer that type of gun ... especially for self defense.
597 VTR, because there's so many cans and so little time!
