Take your Shadow 2 or Shadow 1 from great to OMG!  This will
transform your S-2, delivering an ice crisp SA of 3 lbs. or less.   DA
typically runs 6 lbs. or less using our famous HS-12000 (11.5#) hammer
spring.  Turns the CZ lock work into a precision Swiss watch!  USPSA
Production legal too!  Individual parts cannot be returned for a refund.NOTE:  About 80% of the time the CGW disco will drop
in with no fitting, and 20% of the time fitting is required.  This is
due to tolerance variations from CZ to CZ.  We offer tech support to
make this painless and easy.

As with all precision made CGW parts, the hard parts have a lifetime warranty, even when used in competition.
