Schofield Revolver (Red Dead Redemption 2)

Good day. I ran into an annoying problem. In general, at the beginning of Chapter 2, he immediately robbed the doctor in Valentine and took this revolver from him. Now, after completing the mission where it is necessary to get Mick out of prison, he gave me 2 holsters, and Schofield's revolver disappeared from me (neither in the box nor on the horse). But he showed up at the store. If you buy it, you have to pump it again, so to speak.
How can I return this revolver??? If anyone has experienced this, please let me know.
