Without a doubt the Glock is far superior to the Bersa in respect to quality and caliber.
I have nothing against Bersa. I own one myself and it's a great gun.
My thought on .380 is if you're going to carry one you should go with the Ruger LCP
due to it's ultra compact design and reliability.
As far as other options, there a whole gambit of good choices out there and I'm sure
others will be along soon to share their opinions.
