CZ P-07, P-09, & P-01 Hammer

Tutorial for P-07/09 When installing this hammer in the P-01, 75B Omega, P-07, and P-09 you must also order the 51824 sear spring kit.  Why is this necessary? The harmonics that transfer through the frame during recoil travel into the sear pin can make the sear “bounce” or flutter.  This flutter can cause the sear to loose control of the hammer hook and leave the hammer at half-cock after a round is fired.  The 51824 corrects this and also allows you to tune your SA pull weight to your preference.
