I have a few of these types of holsters,
from some old discontinued ones from the late 80's up
I like this one and would consider this a good one for you
Galco's Kodiak Hunter Chest Holster
most of the one's I have are for Semi auto's over large framed revolvers
carried mostly a Glock 10 mm for a lot of Alaska trips in them,
have one of these
Hosking Chest Holster for Glock
and kind of like iit a bunch due to it stays put better, IMO< so, I find it more comfortable when hiking on odd terrain and bending over often and such!
