My SAO CGW CZ-97B"E" has been my bullseye match gun for the last two years. When I ordered it, I didn't really know what kind of trigger pull I wanted, since the Kadet was a crisp 2 lbs and the P-09 (that I shot really well in 2014 season) was a somewhat mushy 3 lb. I asked for 2.5 lbs and that is what CGW gave me, with their hammer and sear and springs.
Last year I swapped the hammer for another CGW hammer with a little more sear engagement and 3 lb pull. That was better, but the trigger was still a little too crisp for me. Note that this is a personal preference, and is not a criticism of the CGW parts at all. Most folks love the crisp smooth CGW trigger feel. I do too, for a .22. It is me that is struggling with the .45, no one else.
Over the last few months, I've shot a variety of slightly modified and stock pistols with trigger pulls in the 3.5-5 lb range. As long as the pull was not gritty, I could shoot it just fine. The final bit of evidence that confirmed the direction I needed to go was shooting a stock CZ75B Compact, straight out of the box. The trigger was gritty, but the engagement travel was perfect for me. I shot a 91 timed fire target after 5 rounds to check zero. I liked the long creepy trigger! Just like my SIG's.
So, tonight I put the stock original CZ-97 hammer back in the pistol, but left the CGW sear, etc. The only thing I changed was the hammer. After backing out the overtravel and preset screws, I had a creepy but smooth 3-3/4 lb trigger. It feels perfect for me. And me alone. I will shoot it Wednesday or Thursday, if I feel a little stronger than I did today after having back surgery last week.
So another experiment started. I will play with the 97 and "new" trigger feel while waiting for the P-10C. Then I drop everything and concentrate on the P-10C.
Pictures and maybe a video later this week. I'm fired up again to shoot the big ol' heavy .45 after a few weeks with puny plastic 9mm pistols and that wonderful heavy, gritty, 75B Compact.
