P93 is almost impossible to find of the "p" series, I found a like new in the case one about a year ago, it is the only one i have ever seen. The P91 is almost as hard and all the others are getting few and far between too.
Not sure if $550 is too much for you but there is a very nice one on GB right now. It's cycled through a couple times so you might try an offer even. The P93's are on there occasionally but I think they don't give the sellers the right tags in their ad to flag it. I usually spot them by accident.

I'm tempted but I have no more room for another. This one beats my last one a lot.
I just wanted to go back and check on this P93 auction status from the post referencing it above.
Sold for $691.00 + $50.00 shipping. Wow! I can't even afford to buy the working man's Rugers now! It is a good thing that I have all the guns that I will ever need. LOL.
Funny thing was that it cycled without an opening bid several times at $550 and then two people must have gotten excited about it. Was a nice one and they will be fine but people and auctions sometimes makes for funny results.
