When I was in charge of stocking a gun shop, one thing I tried to keep in stock was a small sampling of left-handed holsters for the most common of pistols. But even with only 1911, Glock, J-frame, and sometimes SIG P-series southpaw rigs in stock and a busy sales floor on which to hawk them, left-handed holsters could sometimes get dusty between restockings.
If you wonder why Local Gun Store doesn't have a huge selection of southpaw gear in stock, that's why: Merchandise on the shelf is not profit, it's money tied up that's not turning a profit. It's hard to walk the tightrope between having a wide enough variety of merchandise to be "well-stocked" and being a museum.
With my right arm gimped, I decided I needed a left-handed M&P holster. It's not painful to draw from my current one, but this is a splendid reminder that I forgot a crucial piece of gear* for my carry gun, and one I'll need if I want to give my shoulder a week or so's rest.
Once upon a time, this would have meant a Diogenes-like quest for the left-handed holster (and, if I found one, a vindication for carrying a common gun.)
But not now, for now we live in the future! This is that magic Cyber Monday, when we all look forward to getting back to work, where we'll have access to Windows 95 Pentium machines on a fat pipe instead of the Packard Bell 486 running a pirated copy of Windows for Workgroups with its feeble 28.8 dialup connection we have to deal with at home.
I just double-clicked the big blue "e" on the screen and shazam! It'll be on my doorstep tomorrow. It's like living in the future!
*And no excuse, either, since I had this same problem three years ago when I was still carrying 1911s and fell off Bobbi's skatebike. I've been carrying the M&P for over two years now; I should have already had a southpaw backup holster already.
