Signature guns are all individually designed to customer taste and painstakingly hand-built by Paul himself. These guns receive the maximum attention to detail and fine finishes, but unlike most museum grade guns, they are intended to be used.

Heirloom Signature projects are usually driven by a particular experience or interest a customer might have that is worthy of being implemented into a pistol and handed down to future generations. These guns are often high value variations of combat era pistols and often include a unit insignia, etc.

Signature theme guns are generally the most rewarding for both the owner and the builder because it takes a real commitment from both to make a personalized piece of working art. The guns usually take on the character of the owner through reflection of an interest, activity or even a mechanical item the owner may have an affinity for. This could be anything from Vincent or Harley Davidson motorcycles, P51 Mustangs or an activity like motor racing, etc. These guns are often hand engraved and more often than not finished to museum grade. They are seldom, if ever, fired and are often only handled with cotton gloves.
