I EDC a 49 no dash. It shoots fantastic with Speer Gold Dot Short Barrel 135 gr +P. For a reload I carry an 8 round speed strip in a belt pouch. I got both from Dillon.
"Humpbacks" are a Hammer in a taco action! The hammer slot allows dirt and lint to enter the action over time. I remove grips and side plate, and flush the exposed action with spray break cleaner (points cleaner works great too!) You'll want to do this outside over gravel or a trash can, wear protective gloves! While the innards are still wet with cleaning fluid, I lubricate with one drop of BreakFree CLP. This thins the CLP and it wicks all over before the cleaners evaporate. You end up with a super thin coating of Teflon lube without a buildup to attract grime. Almost every day I check the hammer area for lint fluff and often find it. I just blow it out and move on. A serious action scrubbing is a 6-to-12-month maintenance precaution. My particular 49 had an action job and a silver Metal-life finish before I owned it. It isn't not a beauty queen but an Every Day working gun! I pocket carry currently in a DeSantis Nemesis.
I have reached for it in self-defense twice. It never cleared my pocket before the assailant took off! So I have never fired it in anger. However one very difficult shot I made with it was during my 30-year war with raccoons invading my house. I commonly shot them with the 49 with them sitting on the gutter about 25' off the ground using DA, but one day when I got home from work an adolescent was in a large fork of a limb 35' straight up. I had a window of handball size as he was watching me, I used the single action feature. Square in the face, and one less maker of holes through the soffit into one of the attics! (Moved in 8/24/1984, moved out 9/11/2014) in those 30 years, I killed well over 150 raccoons, most with a CCW revolver! When they hit the ground, they went into a blackberry patch as fertilizer! We ended up with several very healthy blackberry patches! (I lived on a small farm surrounded by corn fields!)
