I've carried either a 49 or 649 everyday since 1975 as my backup, off duty, and undercover gun. In uniform they almost always rode in an ankle rig and were subjected to mud, dust, and snow. I've carried them every place on your body you can imagine and some places you might not imagine. They've gone with me everywhere in every kind of mud, crud, and stuff while doing manhunts in some pretty cruddy conditions wading thru muddy river bottoms, etc. They always work. Those who think lint will get in the lock work have never carried the humpbacks. There's no more room for lint to get in than any other gun. I've treated my 49/649 like I did my primary duty gun. I check them over at the end of the shift and give them a wipe down if needed.
