When I had a 1921 LC Smith featherweight, it did not like over the counter target loads. I think I used Federals a couple of times, but it would hang up on them after firing making the gun difficult to open. If that is the only gun you decide to bring, just make sure it is alright with whatever loads you are going to use before you get out there. That gun was always fine with Polywads. Perhaps you could just ship him some low pressure loads purchased directly?
