shouldn't be a problem, when my buddy can't carry his glock 19 he usually carries a S&W .38 with 2 speedloaders in his pocket.
I've had a big itching for pocket guns in the past few months. I can't carry as i'm only 18, but i can legally own them. I just got a bersa which I am incredibly happy with it and have been thinking of getting a bulldog-style revolver. I don't own any revolvers, but love the look and need practice with them. I really think i want a small revolver in .45LC They just have a certain look to them. If I was carrying one (gimme 3 years), i wouldn't think twice about throwing speedloaders in my pocket.
Obviously your defence ammo doesn't use nickle plated brass....if it was you wouldn't even have the tarnish problem and there would be no chance of corrosion
