Interesting question, and one that was making the rounds back in the previous fed ban on mag capacity (and assault weapons).
Notwithstanding the understandably natural dismay over suddenly being able to carry fewer rounds than were originally envisioned for your Hi Power ... why would you want to carry something other than what you were comfortable carrying and using, and being able to handle and shoot well?
Look at it this way, If you'd actually been in a situation where you'd been forced to fire the Hi Power, and you suddenly had 10 or less rounds remaining in the magazine ... would you have less confidence in the gun, or your ability to use the gun? Just because of the reduced number of remaining rounds?
I don't feel any different about carrying my SW9940 when I carry it with a 10rd mag than when I carry it with a 12rd mag.
Why do I even own 10rd mags for it? Couple of reasons.
Back when I was buying 12rd mags for it, using my peace officer exemption - (I was also carrying the model as an issued weapon at that time) - I was offered some 10rd mags for a bargain.
Then, a couple years ago, when it looked like CA was going to remove the peace officer exemption for honorably retired cops to retain the hi-cap mags they'd acquired before they retired, I decided to order a large, new batch of 10rd mags. Just in case. (And it didn't hurt that I could order them as an armorer, at a healthy discount.
) Well, the law didn't eliminate the exemption for honorably retired cops to keep their hi-cap mags (but we still can't buy any new ones, unless this current challenge to the state's law in the 9th circuit results in overturning the law for everyone). That doesn't mean they won't try again, though, so I'm keeping a bunch of the new 10rd mags put aside "in reserve", just in case.
Bottom line? I'll still continue to carry that full-size .40 even with 10rd mags, like I have in the past.
On the other hand, my compact and subcompact pistols will also continue to see common carry use, as well as my M&P 45FS, with its 10rd standard mags. I just won't be able to order the extended factory 14rd mags, which I think are silly and too cumbersome for carry as spares, anyway.
Different strokes.
6-8 shot revolvers are still 6-8 shot revolvers. Pistols with single digit magazines are still just as capable, practical and relevant.
Now, in this age of double stack pistols being more common than in the days when it was only the M59 and Hi Power models being "common", we may not have as many shooters who are as familiar with single stacks as in previous years.
