Beartrap:
As near as I can figure, this is the "feature" whereby the breech will slam shut if you were to inadvertantly pull the trigger before closing the cocking lever.


Anti-beartrap:
Some sort of secondary device which prevents this?

Does a gun really have to have the latter? I mean if one hand is inserting the pellet, and the other is holding the forearm, or the cocking lever, how's is this even a concern?

If possible, please list some popular guns which display either characteristic.

Thanks!
