Does FMDA G26 frame with Gen5 slide lock spring accept Gen5 slides?

i’m working with an FMDA Glock 26 frame that has the Gen5 slide lock spring

Does this mean it’s compatible with a Gen5 G26 slide? Or is it still designed strictly for a Gen3/Gen4 slide, despite the Gen5 slide lock spring?

Just trying to figure out if I can run a full Gen5 upper on this.

Thanks in advance!
