Same calibers/guns I've carried for many years. Something in 9, .38SPL, .40 & .45 ... only one of which uses magazines of more than 10rds - (12rd/.40) - and I have several 10rd mags for it.
Even when the federal ban came along, and my state enacted its own magazine capacity restriction, I was buying, using and carrying pistols with single digit mag capacities.
I carried one or another hi-cap duty pistol during my career, but I'd started in the revolver days. Back then I'd carried a Commander, Star PD or some revolver off-duty, and I often continued to carry pistols with single stack magazines even while carrying a hi-cap pistol on-duty.
I don't mind carrying my 7 & 8rd 9's, my 7 & 9rd .40's or my 6-8rd .45's. Matter of fact, I finished my LE career carrying an issued 7+1 compact .45 in my plainclothes assignment, and I didn't feel ill-equipped or "under gunned" at all.
Then again, this is the opinion of someone who often carried, and still carries, 5-shot J-frames on my own time.
