As with their right handed electric guitars, PRS SE Custom 24's dominate. The most popular colour is Trampas Green. Both SE models and Maryland-made Core Custom 24's are popular with lefty players.

Which guitarguitar stores keep stock of left handed PRS guitars?

All of our stores keep stock of the SE guitars, normally in a variety of finishes. Since the Maryland built Core line is never in regular supply, stock location for these is harder to determine. Click through to the product page of any specific guitar that catches your eyes and you'll find details of that guitar's location.
