Depending on the design you can fire SA/DA with a striker fired weapon and not all require the trigger being pulled to disassemble. As for readiness, that doesn't make sense. Sure the hammer is cocked, but is a round chambered? That is the question. If a round is chambered the given pistol is ready to go.Hammer pros:
- Tactile feel for readiness, especially on SAO pistols.
- Visual indicator if the weapon is cocked or not.
- In every case I have ever heard of, a hammer transfers more energy to the firing pin.
- On a DA or DAO style design, the hammer offers a double strike capability of dubious value.
- On SA C&L designs as the trigger need only trip the sear and the potential energy in the larger mainspring drives the hammer, one usually can get a much better trigger pull on a hammer fired pistol than on a striker fired one.
- One could, I suppose, cock a down hammer manually to threaten someone if necessary. With a striker fired pistol, you have to shake it at them or something.:supergrin:
- Could possibly snag on clothing though hammers can be modified.
- Is open to environmental obstruction.
- There are more parts in the frame in order to power a hammer with a mainspring.
- On certain designs, the presence of a hammer calls for a DA/SA trigger set-up, which many people loathe.
- Creates a more streamlined design.
- Less prone to be badly exposed to most forms of environmental blockage.
- It's easier to change out the striker, spring and any sub-assemblies than it is to change the hammer out on most designs so equipped.
- On many such designs, it is difficult to tell the readiness of the pistol.
- A striker, by limitations of its design and relatively smaller spring drive, cannot hit a primer as hard as a hammer.
- The design is incapable of a second strike.
- Striker fired pistols can often not be field stripped until the trigger is pulled or the sear somehow released, which has proven dangerous to the complacent.
