I bought a 2 stage for mine, but it's not here yet (my V22).
I asked in the V22 thread if the standard size BnA sear will work, but no-one responded.
Only worry I have is how they will hold up in the dirty rimfire environment, they say to run them completely dry, which I like.
I"ve fought Jewells before in the dirt, and don't want the headache.
