If I have my LCR on me, pocket carry, it's because I'm feeling relaxed yet prepared, if that makes sense. I DO have two bianchi 5 round speed strips, but unless I'm not at home (at a hotel where the LCR is serving a primary role) they usually stay in my gunvault/lockbox.
At night my XD9 is my primary weapon and I have 4 loaded mags available plus the one in the gun to use. These live on a dedicated gun belt that I can deploy that also has shingles with two AR mags. (this not a response to perceived threats in my area, btw. More of a " just want to have everything in one place" type of setup.)
So if my primary assessment is that a handgun won't suffice, all I have to do is unlock my AR and in addition to the mag in the gun, I'll automatically have two extra.
At some point, if I thought of it, I'd probably drop the LCR in a pocket, along with a speed strip, but my setup with the belt is taking into account that I'd probably just have a tshirt and chonies on due to it being o-dark-thirty. At no point would I likely think to grab the speed strips, but maybe I should put at least one in a pouch on my gun belt.
Anywho, that's my experience/thoughts on where those "funny little speed strips" fit in my overall plan.
