Update: my parts came in today and late this afternoon I FINALLY had time to start installing them.
SRS Kit
#18 Hammer Spring
Reduced Power Trigger Spring
I must say, I watched 3 different videos about a zillion times. Actually, given that I've never stripped my CZ down this far I am amazed that everything is back together with the new parts and there aren't any left over

Next weekend I'll function test with live ammo and for now I'm using a little revolver for bedside and carry. The gun seems to function properly but has to be tested with live ammo of course. I especially need to make sure the extended firing pin is OK. It seems that sometimes it sticks out just the very slightest bit when it's not supposed to be. But maybe that's OK and maybe it will stop doing that, I don't know. Anyway, can't wait to get to the range.
Now for the drama..........I was ready for those "flying springs" but of course first thing I did was let the little spring under the ejector fly "somewhere" in my dining room. The shocking thing is that I found it. The rest when pretty good until it came time to re-install the decocking lever spring. OMG, what a PITA that was, took me forever to get the little "leg" hooked. Didn't help that I couldn't really see good and had such poor lighting that I was holding one of my weapon lights in my mouth....LOL.
I next discovered that I HAD to use the new roll pin that came with the SRS (well, that's what someone said on the internet on one of the videos). Of course I had used the old roll pin since it looked good. So I took out the old roll pin and re-installed the extended firing pin with the "new" roll pin.
On to the reduced power trigger return spring.........I only THOUGHT that the decocking lever spring was bad!!!! That darn trigger spring......OMG.......I let it fly about 8 times and once again can't believe that I found it each time. I dropped it on the table a zillion times. I saw a video where the trigger was removed and the spring was captured with a slave pin and then the trigger put back in but I was being lazy and didn't want to do that (why of course not, why do it the easy way).
Bottom line it that I learned tons about my CZ P-07 and would do it all over again (well, except for those 2 darn springs). I'll post my range results next weekend.
DRUM ROLL.............
I can now pull the DA trigger with my weak left hand so I can continue to carry in my left hand holsters. Now that I've achieved a lighter DA pull, I'll do some of the polishing that is recommended to get my P-07 even smoother. The SA reset is fabulous!!! When I'm at the range I'm going to have the DA and SA pull weights measured just so I'll know. Too bad I hadn't done that before the updates.
