Just got from a widow of a police Sgt. a model 12-2 and a model 42 lemon squeezer, I think that is what it is called. The 12-2 has some holster wear just on high spots, the 42 not so much, both are good and tight, they don't look like they have been shot much just carried. Just looking for approximate value thanks? Another question do the 351C or PD have the internal lock, any one have one and how good are they, the gun not the lock, I am thinking of getting one ? I have a 317 that I bought in 1997 it is a great shooter and it has not given me any trouble since I bought it, I carry it every day as a backup for my 6906. I forgot Both have tyler grips and both have 1 7/8 in barrels.
