121 training obviously makes you 121 current (for landings and IFR).
You can also count a 121 PIC proficiency check for part 61 instrument currency. Part 61 is clear on this, which excludes an SIC check.
If you are already part 61 current current an SIC can use approaches/holds/intercepting/tracking conducted as an SIC to stay 91 current. This is legally current, not safe or proficient in part 91 operations...
But an SIC who is not 61 current (and out of the grace period), needs an IPC. 121 training would probably cover all of the required items, but you would still need an IPC endorsement from a part 61 CFI. Many airline instructors are not CFI's, 121 allows this for 121 only...they cannot do part 61 endorsements or flight training. If he happens to be a CFI, they are often reluctant to sign your logbook for part 61 purposes due to liability concerns. I wouldn't do it in their shoes either because being instrument current in a glass turbojet is not the same as being proficient in steam-gauge piston ASEL.
