are there any other triggers besides SAV-1 & SSS for 111 with triggerguard bolt rel?

[KAIFS]

I would like to find a SAV-2 (Rifle Basix) type of a trigger that will work in my wife's 111 Lady Hunter (rechambered to 6.5x55) LA (original 270win configuration) which has bottom (triggerguard) bolt release.
There is so much money went into her rifle already and trigger is the last sucky part that needs to be improved for a 'perfect' rig.
Thank you for any help.
P.S. I am well aware that SAV-1 and SSS (with some 'fitting') will work with that type of a release.
P.P.S. ultimately, if there is a great bottom metal with a side release that will drop in with minimal wood releaving, I would be all ears if an exact part number can be furnished.
