I talked to someone at Coles this am. It was a really bad connection for some reason, and we actually got cut off so I didn't catch the last part, but what I got was that parts for the BL series Berettas are no longer made and not available.
My assumption is that it would cost more than the gun is worth to have a conversion done with that being the case.

At least my gloved finger will fit nicely in colder weather!
