Frequently Asked Questions

What are the safety advantages of Double Action/Single Action (DA/SA) pistols for concealed carry?

DA/SA pistols with external hammers provide a tactile safety feature. When reholstering, placing a thumb on the hammer can alert the user if the trigger snags on clothing or gear, preventing an accidental discharge.

How is the Sphinx SDP Compact constructed, and what makes it unique?

The Sphinx SDP Compact features a unique three-part hybrid design: a steel slide, an aluminum upper frame, and a polymer lower grip. This construction aims to balance durability with a manageable weight, offering custom-level fit and finish.

Is the 'second strike' capability of DA pistols useful for clearing malfunctions?

While DA pistols have a second strike feature, it's not the recommended method for clearing malfunctions. Immediate action drills, such as 'tap-rack-bang,' are universally faster and more reliable for clearing failures to fire or feed.

Why is appendix carry considered advantageous for self-defense?

Appendix carry offers quick access to the firearm, especially when seated, such as in a vehicle. It allows for easier retention and less obstruction from seatbelts compared to other carry positions.
