Does anyone make a replacement trigger for M700's that maintains the bolt lock feature of the older design? I have 2 made in Dec 69 and Jan 70 that are the design where the safety locks the bolt and I would prefer to keep them that way if I replace the triggers.

No trigger replacement I know of does that as long ago it was decided that having to disengage the safety to unload was foolish. However, Gentry made three-position safeties that uses the original trigger and locks the bolt down when in the third position.

Thanks John,
I found the upgrade kits from Jard. Looks like that is the way I will go.
