Some food for thought, this comes from an instructor and snub nose "expert". The thought is that in a J frame you only reload 4 rounds. When the SHTF speed is needed, and if your reloading your in deep. When reloading you put two rounds in at a time off the strip. So its two, two, close cylinder. Other wise it takes 1/3 the total reload time to load one round. Also part of the advice was to have two strips with four each. So you will have 13 rounds vs 15 but you are faster reloading. Oh also when you close the cylinder with 4 rounds you wont know where the missing round is so if it clicks just shoot again...
To me it makes some reasonable logic...
