I don't see where it is strange to carry a different set-up for different situations. I know there are those who cringe at the thought, but it works for me.
Most days, I am working in high crime neighborhoods. I carry an XD-45 with 10+1 in the gun and a spare 10 rd. magazine. Why not the 13 rd. mags that came with the gun? Because the socialist state where I spend most of my day doesn't allow any magazine that is capable of holding more than 10 rds. into the state. Unless of course, the magazines were manufactured prior to 1984. Being that the XD didn't even exist prior to 1984, it would be a hard sell to convince a judge that the magazines that fit it were.
I could carry twenty 10 rd. magazines, but one 13 rd. magazine will apparently cause me to take out a Burger King or something!

Also the Glock boys can carry a bazillion rd. mags because they are "Pre-ban". Ridiculous.
Back to the topic. When I will not be in those high crime places on a given day, or when I am just running down to the store for some milk after dark, I drop the 640-1 in my front pants pocket. I bought a Tuff speed strip holder that I really like. It holds two 6 rd. speed strips very flat and accessible on my belt. I know the revolver holds only 5 rds., but I keep the speed strips loaded with 6 in each. That is in case I fumble a rd. during a reload. That is a distinct possibility because in all likelyhood, I will be running at the time!
When not in a socialist state, the XD-45 with one spare magazine affords me 27 rds. of .45. If that doesn't get me out of trouble, nothing will. I have contemplated carrying two spare 10 rounders with 11 in the gun when in the socialist state, for a total of 31. The jury is still out on that, because I am thinking that 21 rds. is still plenty.
The j-frame in the pocket is most comfortable, and has plenty of knock-down power with the .357 mag. Speer 135 grn. Gold-Dots, but it isn't the same feeling of security I get with the fully loaded .45.
I practice plenty with both set-ups, so I am comfortable with either. I think that is what's most important. Not what you carry, as much as how much time you put in to be fast, accurate and confident with it.
