Here are a couple of links to find parts for 742's.
Your gunshop owner just didnt want to deal on the gun. my buddy can't keep them on the shelf. in south arkansas they seem to be hot sellers. i have thought about selling mine that i have had now for some 24 years. just because i never hunt with it or shoot it.
oh and by the way mine has never jammed on me or let me down.
