Looking for any advice on holsters for newly acquired Tracker 627, .357 mag 7-shot, 4" barrel revolver. Will it fit holsters for the S&W 66 or S&W 686 or something else? Thanks, any experiences shared will be appreciated. I have heard both sides, some saying it is close to the S&W K-frame, others that it is close to the L-frame, and yet others saying it is a hybrid between the two. Thanks again in advance.
