which wwii luger should I be looking for?

[Brien]

I have added a wwii luger to the list of pistols I'd like to add an example of to my collection. I am looking for something midrange. Authentic, in good condition that I could conceivably take to the range every now and again.

I am kind of stumped as to what to set my sights on. A letter code? A byf, an S/42?????? I get confused with all the special terms/selling points. Krieghoff, sneak pistols, black widows etc. I know some are just marketing.

What would you folks recommend? I am thinking maybe a byf or s/42??

As always, any reply is greatly appreciated, so thank you in advance for taking time out to answer
