- Thot I'd lost a OWB, but it's ok. Turns out it's the pin/spring deally behind the backplate. I'm thinking that it poss gummed up a lil over the winter and sprayed a little WD40. It helped, but the engagement seems sporadic. Wondering if the spring has lost some tension. Does it just pull out, can I stretch it a little ? It seems to be housed in a rubber type collar ?? Never been inside the 46. Thanx for any input
