Hello dear users of this wonderful forum. I'm reaching out to you with a request for opinions. I'm planning to purchase a Smith & Wesson Mod.460 XVR, 8 3/8inch revolver, but I'm concerned about the type of screws used in the side plate. Have any of you ever seen this type of screws in S&W revolvers? The revolver is described as used but not fired, so it's almost like new. I've looked through many different videos on YouTube and pictures online, but I haven't seen such screws in this model or other S&W models. I would appreciate your opinion. Thank you very much for any help before making a decision on a potential purchase. Regards.
