I normally try not to post in zombie threads, but my thinking has evolved somewhat since my earlier posts.
I still think that if you carry a K-frame with a J-frame BUG, a speed strip makes a lot of sense.
However, since I only have J-frame carry revolvers now I've switched over to speedloaders for a few reasons.
I used a Simply Rugged strip pouch to hold my main reload strip at my left hip (I use the deBethencourt reload method where the gun stays in the right hand). The problem was that occasionally the snap cover would pop open when getting in or out of the car due to the seat bolster.
I've used split-six type pouches with my Safariland Comp I speedloaders, but again the seat bolster would occasionally pop the cover flap. Fortunately, the loader only fell inside the car. Also, while it hasn't happened to me, I have heard of instances where enough pressure was applied to the speedloader that the belt it straddled tripped the release mechanism, spilling rounds all over the place.
A couple of years ago I discovered JOX speedloader pouches, and they have been the best solution I've found to carrying speedloaders. They carry the speedloaders above the belt, which minimizes their profile. The kydex secures the loader in place yet allows for quick and easy release when needed. And they come with foam liners that keep the loaders from rattling in place. I now carry 2 speedloaders on my belt.
My main reason for prefering speedloaders now has to do more with secure handling than speed. Yes, I can load a second or two quicker with a speedloader, but more importantly I can reload with less likelihood of fumbling. And if I do fumble and drop a speedloader during a reload, I've got a second speedloader on my belt.
Of course, needing to reload during a gunfight is highly unlikely. In the rare instances where a reload has been done, it had virtually no effect on the outcome. However, that doesn't mean I want to stand around with an unloaded gun if I'm forced to fire in self defense waiting for the police to arrive (average 911 response time in my town is around 9 minutes).
As for the tactical reload of a revolver, or reloading a partially empty cylinder with single rounds, whether from a strip, dump pouch, or belt loops, doesn't make sense to me. With a semi-auto, it can work. It's not a difficult task to swap out magazines. But trying to press up on the extractor rod enough so I can pick out empties, and then reload only those chambers, all while likely having at least somewhat shaky hands after the adrenaline dump from a self-defense encounter, sounds like both a waste of time and a good way to fumble the reload. I don't practice tactical reloads. If I have to fire and then reload at some point, I just dump whatever's in my cylinders and reload with my speedloader, a process I can do without taking my eyes off my environment. One, it takes less time; two, it doesn't require as much dexterity; and three, it simplifies my practice regimen.
Just my thoughts on the matter. For now, anyways. Maybe if this thread gets resurrected again 6 years from now I'll have changed my mind.
