They can be a pain to carry concealed but I have never had a problem with them loading. What I do is put some in my truck or the wife's car, usually in the ashtray or the other little compartments like pop out drink holders. That way you always can reload in your vehicle and if you feel you may need extra ammo just throw one in your pocket. I switch my carry gun from a 44mag/spec to a 45acp. The 45acp is really handy because of the moon clips, it is like a drop in speedloader. I have only used HKS brand and can not speak of the others like the jet loaders used in competition shooting. Hope this helps, James.
