So the LCP (ie LCP 1) hammer is DAO, and will rest partially back when the gun is cocked (ie ready to fire). The bottom of the hammer should be just a hair below the line (the line that is the divide between the slide and frame). This has nothing to do with a round being in chamber per se. But, being cocked, you could fire said round by pulling the trigger at this point, the hammer continuing to move back and then fall. You could dryfire too, but only once without resetting the trigger by racking the slide.
If the gun is uncocked (ie you rack the slide and then pull the trigger without firing a round), the hammer should disappear,
being in the full up position against the slide. You can not pull the trigger (ie trigger is dead, still moves though, just doesn’t move the hammer).
Since the hammer is flush with the back of the gun, and you’d have to rack the slide to cock the gun, it seems unlikely that your holster is the issue. This is not an SA gun (like a 1911) where you can easily cock the hammer. You really could in no way cock the hammer on an uncocked gun.
Does all that make sense?
