  3. David D.

    It’s an auto sear release that matches the SIG patent design. Product is very well made. Does not convert Rattler or Virtus to full auto. It’s a great quality replacement part.

  4. Taylor P.

    Exceptional quality, fit and customer service all at an incredibly reasonable price. And all of this for Sig Sauer products to boot. PMM is a dream come true!
