SP101 is a great gun with only 5 rounds. Most of us are slow and sluggish on revolver reloads because we don't practice like we should. Speed loaders are fast but bulky and a pain to carry. Also, be careful about after market grips becasue many (if not most) block speed carriers and my even interfere with ejection. I have some eagle secret service grips that will block the spent casing from ejecting next to the frame
Speed strips are slow as waiting for toast but easier to carry. I carry one speed strip loaded "2 space 3" in my right front pocket if my revolver is strong side IWB. If I'm pocket carrying the revolver, then I wear a speed strip pouch that I bought off the dillion press web site for $26.00. It's okay but has a silver snap on a black leather holder. Problem with this is anyone who knows anything about revolvers knows what you're carrying and that's ALWAYS bad so I've started carrying a strip in the front left hand pocket which makes for awkward reloads.
With a 5 shot J frame you either hope and pray it's over before 5 are spent or you're moving for cover as you reload and trying to dissengage. It's not very realistic that'll you'll be blasting away toe to toe and then reloading a J frame and continuing to shoot without having been moving away from the target at an angle seeking both cover and concealment. If not, and the bg is still shooting you're in BIG trouble unless they can't hit the broadside of the barn.
So always carry at least one speed strip as a minimum. Another option is to by a regular mag belt pouch that will fit. HBE Specialty Leatherworks will make you one to fit a speed strip of .357 or .38
This is one of the weaknesses of the revolver over an auto.
CCW is all about compromises.
