I carried mine in the small of the back, IWB under a sport coat for four years.
I moved to it from a Colt Mustang.
I learned to draw from concealment and fire all 8 shots at 8 yards in under three seconds. This "Bill Drill" or "mag dump" tactic is the great strength of the gun. 380 ACP in a straight blowback design. Anyone who does not know exactly what is meant by blowback, should please read up on it before you buy this.
The base mounted magazine release took some practice. I use the support hand to do all administrative functions on all pistols and never loosen or move the firing grip. My left hand does not seem to care which gun I am using. Even so, do not consider this mag release type to be fast.
I do not know any advantage to the West German earlier gun over any others. I got the stainless, but the finish on the blue guns is excellent.
I do not know what changes were made in the P232. For my purposes it was the same in every respect except the 232 grips are ugly. If I had one of them, I would not want the other.
My mother shot her Bersa 380 very well. After she passed away, then my Dad carried it in a shoulder holster. He was very satisfied with it. I think the quality difference between the Bersa and Sig is dramatic and obvious.
The PPK fights the same way, fills the same role, but again the Sig fit and finish is superior.
I have now a Smith 3913NL, loaded with Hornady Critical Defense Lite, the ones with the pink tip. It carries and shoots very reminiscent of my old P230 because that round converts the 9mm into a 380 for the ladies. (What in the Sam Hill?)
I paid a little over $500 in 1987, IIRC, which translates to $1,400 today.
I used a Bianchi suede IWB clip holster which was modified to fit by a shoe repair shop.
Kind Regards!
