Not sure what's going on here but the last few times I've flown with my G48 in a checked bag, the gun has "alarmed" on the TSA swab test resulting in a wait for a supervisor to come and re-test.
Between the first time and today, I've changed out the transport case for a new one, so that's not it.
The G48 slide was refinished in black nitride, if that's relevant. I do clean it.
Is this happening to others, or just me?
