DementedAntics Posted July 23, 2017 Share Posted July 23, 2017 (edited) Which spring mods are an easy thing to do for a beginner to clean up the sa/da pull? What mods are the best bang for the buck before diving in for full production legal kits? I'd like to slowly buy parts overtime to build a production legal Sp01.

Ken6PPC Posted July 23, 2017 Share Posted July 23, 2017 I'd say an extended firing pin with reduced power FP spring and main (hammer) spring. https://cajungunworks.com/product/54420-ultra-lite/ Link to comment Share on other sites More sharing options...

If so thoughts? I see that it says 50% reduction in DA any change in he SA pull? would you recommend an 11# recoil spring also? Is it known what those main spring weights are for black and blue? Thanks for your help. Link to comment Share on other sites More sharing options...
Ken6PPC Posted July 23, 2017 Share Posted July 23, 2017 (edited) Yes, I put a similar set (#54440) in a CZ 75 Pre-B. I was amazed how much it helped. Won't help with slack take up, or improve the reset, but the springs made a dramatic difference from the stock springs. Note that they do not recommend this for concealed carry! I used the lightest hammer spring (8.5#), and was expecting some misfires because I was using CCI primers. I had no problems at all! Even the 11.5# made a huge difference. Oh, I forgot... The "best" recoil spring depends upon your load, and personal preference. I use either 10 or 11 pound springs, but I am shooting a light 147 gr. reload. This will help you determine what is best for you: https://cajungunworks.com/product/tuners-pac-music-wire-recoil-springs/ Edited July 23, 2017 by Ken6PPC Link to comment Share on other sites More sharing options...
DementedAntics Posted July 23, 2017 Author Share Posted July 23, 2017 I plan on using this as solely a range/competition gun. Link to comment Share on other sites More sharing options...
rowdyb Posted July 23, 2017 Share Posted July 23, 2017 Change your main spring to a 13# or 11.5#. Change your recoil spring to 11# if shooting 147gr bullets. You can get buy with the standard firing pin for a while, but a reduced power one here is nice too. Either source these from CZC or CGW. Recoil spring involves a basic field strip. Firing pin spring involves removing the plate. Main spring involves removing the grips, two pins and the mag brake. Even if you are completely mechanically disinclined you can still eventually muddle through these three things, especially watching a video of it.

rowdyb Posted July 23, 2017 Share Posted July 23, 2017 Truly the best bang for buck is a very well done polish job of all the appropriate parts. Link to comment Share on other sites More sharing options...

So, his pistol doesn't have a FP plate. It will have a firing pin retaining pin, and a firing pin block. Just don't want to confuse him. Of course, it is still pretty simple to pull the FP and swap it out... Link to comment Share on other sites More sharing options...

rowdyb Posted July 23, 2017 Share Posted July 23, 2017 Kneeling Atlas' tuning guide here in the CZ section is the definitive source. Follow it to the T and you'll be happy and much more knowledgeable and comfortable about your gun. Link to comment Share on other sites More sharing options...
muncie21 Posted July 23, 2017 Share Posted July 23, 2017 Once you finish with the springs and firing pin stuff, I'd suggest putting in the Cajun 10x bushing. It really improves barrel fit in the slide, resulting in better accuracy (provided you do your part) Link to comment Share on other sites More sharing options...

DementedAntics Posted July 23, 2017 Author Share Posted July 23, 2017 So here is what I have in my cart. Looks like I have all that I need? I was looking at your build thread @rowdyb and matched the parts you have and advised. My next question is, can I basically build the competition package from CGW overtime if I wanted or will I have to toss these parts and just buy the bundle they have. I think all I'd have left would be a hammer and trigger correct? Link to comment Share on other sites More sharing options...
rowdyb Posted July 23, 2017 Share Posted July 23, 2017 (edited) For stuff that's plug and play that's a great shopping list. The trigger return spring can be a challenge unless you are comfortable doing a detail strip of the gun. But if you're bascially mechanically inclined you'll be able to get it with only mild cursing. And it does help reduce the DA trigger pull. I'm not super familiar with all of CGW offerings, so not sure how to advise you there. But yeah, eventually a hammer will be nice. For me, the trigger is all about your reach and the feel of the shoe on your finger. Edited July 23, 2017 by rowdyb Link to comment Share on other sites More sharing options...
bowenbuilt Posted July 23, 2017 Share Posted July 23, 2017 I'd say you have done well in choosing your parts. Get ready though, when the bug bites it digs in hard. Cajun Gun Works has the bug. I know you will enjoy it and also the 5 to 7 more you will buy right after it. Link to comment Share on other sites More sharing options...
Ken6PPC Posted July 23, 2017 Share Posted July 23, 2017 Those parts will help your SP-01 a lot, but be careful. It is a "slippery slope" to where you have put more money into your pistol than you intended! At some point, it may be better to buy what you wanted to start with.

I don't know which is better or what to go with. 1 hour ago, bowenbuilt said: I'd say you have done well in choosing your parts. Get ready though, when the bug bites it digs in hard.

Yea your right about that, my M&p9 was my production gun I planned to shoot forever and get better with. Next thing I knew I got a great deal on a Trijicon Rm06, magwell, and full apex trigger and it's basically a carry optics or open gun Hahah. In truth when I'm done could I have bought a shadow2 or a tangfo stock2 like I wanted? Yea. But I do love tinkering with guns and I do love buying more. All the reading I've seen says you can get about 90-95% of a shadow with a modded Sp01 (I know it will never be as good as a non-fpb CZ) how true it is idk. Y goal is to get my gun shooting as best I can for a good deal. So if in theory and reality I spend $1100 total on an Sp01 and mods and could have gotten a shadow for 900-1k, oh well, I spent $1-200 more but at least I will have learned a lot and I will still have a sweet shooter from what I've seen/read (fingers crossed hahah).

twowheels Posted July 24, 2017 Share Posted July 24, 2017 While you're on the CGW site, you could also get a comp hammer, an adjustable sear, a short reset disconnector, some new sights. Might as well go all the way. My tuned sp 01 is pretty darn close to my tuned shadows. It's only money and time. Tuning CZs is a great was to spend some time tinkering and what comes out the far end is a joy to shoot. Link to comment Share on other sites More sharing options...

If you disabled it, your pistol is illegal for most competition. Link to comment Share on other sites More sharing options...
muncie21 Posted July 24, 2017 Share Posted July 24, 2017 Hi OP, if you're going to replace the trigger return spring, you should consider getting the CGW floating trigger pin. Not trying to send you down a slippery slope, but there's a chance you could damage the original pin (I believe it's hollow) during removal.

I left it in. I polished it and put in the cgw reduced power spring. It has a slightly longer reset than the shadows but its a pretty slight difference.

Just finished putting in extended firing pin, reduced power FP spring, and 13# main hammer spring along with some polishing of firing pin channel and mainspring strut during the process. Just these extremely simple steps reduced my SA trigger pull from 5 1/2 pounds to 4 1/2 pounds. and definitely feels better. Eric Link to comment Share on other sites More sharing options...
