Yeah, it looks like TargetSports is out of the 135gr Gold Dot load as well. I’d love to find some. I have the LSWCHP so I guess that’ll be good enough for .38 needs.
For .357 I just got 175 rounds of the Critical Duty and I have a couple hundred rounds of Remington 158gr SJHP on the way. As mentioned before, I like the CD’s middle of the road approach to .357, but not sure I can find an adequate practice load to mimic it. Unless maybe I found a load that feels the same and sight in a dedicated trainer GP100 purely for said practice load, but that seems a bit impractical.
