It wouldn't. The minimum size for my primary pistol is decided by sight radius and grip size than ammo capacity. That size would be something like a Sig Sauer P229 or Glock 19. Even pistols that does not meet the mimimum size for primary pistol can fit 10 or more rounds of 40S&W in it. So, I won't be carrying anything smaller, just because there is a capacity restriction. I do have pistols smaller than that, but those are secondary pistols, and the smaller size is to deal with restrictive concealment requirements, not lower capacity. Since 40S&W is already at the limit of what I can control at speed, I am not going to carry anything more powerful, even if there is a capacity restriction.
