i've got a few examples.. one near mint.. ( ok.. maybee very good? )I can assure you it can be opened cocked..
while it could be damaged.. it looks nice enoiught that it may have been fired only a handfull of times. doesn't even look carried much.. extremy light holster wear, and wear on hand contact parts.
i have a feeling there may be spring strength issues though due to age perhaps contribuiting to the issue. ( maybee? )
