Are you saying you carry both at the same time, one as a backup? Or that you alternate carrying each?
I shot a nice Taurus when I took my handgun classes.
No, because the Bersa mags are so expensive, I have taken Taurus mags made by Mec Gar and made a mage release cut in them to use in the Bersa as backup mags. I carry only the Bersa ... and a five shot 22mag mousegun backup.
