Gary,
H&R factory firearm triggers can vary from 3½lbs-7lbs, older frames typically had very heavy triggers, but in the last couple years they've improved a lot, those that I've bought new with one exception that were made 2006 and later have had very nice 3-4lb triggers. Gardner occasionally charged $20 for trigger jobs if the pull weight was already under 5lbs, but I can remember only a couple that reported being charged, but hundreds that got free trigger jobs to about 3½lbs, usually done with an accessory barrel order or a repair. I think Lonewolf5378 had one done at Ilion, and I know Swampman had one done there, Swampman's was free along with a second hand barrel fitting, I think Lonewolf's was $15, but I don't remember for sure, that may have just been the return shipping charge.
