Honeybooboo Posted August 14, 2015 Share Posted August 14, 2015 I know there's a lot of info out there but I'm going to get a sp-01 shadow to play with. I don't want to wait the 8 weeks to have cz custom change parts out so I was thinking of starting out with a plain stock shadow. But is there anything that really needs to be done? Was going to have them install the comp hammer, cz85 trigger, polish the feed ramp and leave it at that. But yea don't know if it's worth the cash and wait time? I've only handled a stock cz75 before and thought it was pretty damn good except the weight of the trigger pulls. Figured with the shadow id have a better trigger right away without doing any work to it. Link to comment Share on other sites More sharing options...
jogan Posted August 14, 2015 Share Posted August 14, 2015 You'd be surprised how good the shadow trigger is in it's stock configuration. Give it a shot before spending money on it. Link to comment Share on other sites More sharing options...
hlpressley Posted August 15, 2015 Share Posted August 15, 2015 The stock Shadow is great, but it only gets better when you add the custom parts and start tuning. Link to comment Share on other sites More sharing options...
Pinka Posted August 15, 2015 Share Posted August 15, 2015 At least order some lighter springs, cant remember what it ships with but springs are cheap, my 11 pound main sets off winchester primers without a problem. Link to comment Share on other sites More sharing options...
brisix Posted August 15, 2015 Share Posted August 15, 2015 13lbs CGW hammer spring, 11lbs recoil spring, extended firing pin with reduced power firing pin spring, CGW reduced power trigger return spring and his floating trigger pin. All very easy and low cost mods, total $59. The stock hammer is pretty good and argued by some to be as good as the comp hammer. Next level upgrades is the Type 1 dis-connector for eliminating most of SA pre-travel. If you don't mind doing a little hand fitting the type 3 is the way to go. I would also recommended getting 11.5lbs and 8lbs hammer spring and the recoil spring pack to figure out which spring combo works best for you. Give David at CGW a call he will get you the parts you need. Link to comment Share on other sites More sharing options...
Honeybooboo Posted August 15, 2015 Author Share Posted August 15, 2015 Yea having someone fit the type 3 disconnect would be huge because I hate pre-travel in single action. If there's pre-travel in the trigger after the reset I can't stand it. Link to comment Share on other sites More sharing options...

If there's pre-travel in the trigger after the reset I can't stand it. Interesting, I prefer a little. I like it for when you move across a stage and have to remount the trigger. I find that little bit of take up prevents me from sending an errant one into the berm Link to comment Share on other sites More sharing options...
rhart123 Posted August 16, 2015 Share Posted August 16, 2015 (edited) I just picked up a 91154 Shadow Custom from CZ Custom shop. It comes with competition sights, cz85c trigger already installed and extended mag release. The double action pull is fairly stiff, but not as bad as some I've handled. The single action trigger pull is close to that from a CGW competition hammer only with a very small amount of creep before the break and zero camming of the hammer - I might keep it for a while before switching out. This gun is very accurate - it shot a 25m 1.25" group from the bench even though the test target showed 1.530" test group (I'm assuming that was with a ransom rest). It's advertised as a CZ Custom exclusive and the hammer is similar to a CZ Champion. Any way, I think with a hammer spring change and an extended firing pin this one could be good to go for competition. Took only 3 days to get it!

twowheels Posted August 18, 2015 Share Posted August 18, 2015 Buy a stock shadow if you can find one and then decide after you get it what mods you want to make. I have an sp 01 shadow custom and a stock 75 shadow. Before tuning, the triggers were pretty close. I've done considerable tuning to both of them including the mods mentioned here. The triggers are now indistinguishable. And the stock shadow is of course a better value. Link to comment Share on other sites More sharing options...

Also found a couple places that have the cz custom sp-01 shadow customs in stock. For $400 more it seems like the way to go. Not sure if the sp-01 custom is idpa legal though. Might not be because of the hammer. Don't should idpa but may want to have that option. Link to comment Share on other sites More sharing options...
twowheels Posted August 28, 2015 Share Posted August 28, 2015 I am pretty sure the custom shadow is IDPA legal as long as it has fixed sights. The adjustable sight models have milled slides which renders them not IDPA legal. IMO the fixed sight is the way to go in any event. Link to comment Share on other sites More sharing options...
zen_grasshopper Posted August 28, 2015 Share Posted August 28, 2015 I just picked up a factory Shadow to be my backup/practice gun to save some wear and tear on the Accu. This is what I am doing to it. Replace front sight with Dawson, factory is too wide Replace safeties with thin Rami style Extended firing pin CGW Type 1 disconnector or pre-b disconnector CGW floating trigger pin Steel guide rod 11lb recoil spring 13lb hammer spring SSI scale grips, probably in red This will make it as close to my Accu's setup as possible without paying more for the Comp Hammer and stuff I don't need. My Shadow has a darn good single action pull and the DA isn't that bad, but the weight could be dropped a bit. I don't chase super light trigger pull weights, I don't mind them a bit heavy.

May have my gunsmith polish stuff up as well because he does it for most of my guns and does it real cheap. For 100 bucks or so I can have all those parts, installed, and the trigger parts polished up. Link to comment Share on other sites More sharing options...

IMG_0130.jpg Nice. I like the idea of thinner safeties. May have to do that. Side topic, but what is the accuracy difference between a regular shadow and an accu at like 25 yards?

zen_grasshopper Posted August 29, 2015 Share Posted August 29, 2015 The Shadow will most likely shoot 3" to 4" groups at 25 yards. The Accu around 1.5" at 25 yards. Both with good ammo, and a better shooter than me. I only got the Accu as my wife wanted to get it for me for my birthday, and why not? Link to comment Share on other sites More sharing options...

I find that little bit of take up prevents me from sending an errant one into the berm +1 here . Had problems getting the cgw drop in to work & ended up installing the cz custom drop in, I think that is pretty rare though. Don't see the DSPerman increased weight safety springs mentioned anywhere. I bought a 5 pack ,cheap at $14.95 and takes the stress out of losing one, if you are one like me who can occasionally bump the safety while running a course they are a good thing. Else , op, if you have a go at doing things yourself you may get addicted, to get started for parts I just called CGW and bought what was recommended after studying the website. I'm tempted to buy another stock SP01 just so I can work on it . Link to comment Share on other sites More sharing options...
Timido Posted August 29, 2015 Share Posted August 29, 2015 I have a stock shadow sp-01 with drop in disconnector 13pound hammer spring and extended firing pin. So far I really like it. Anyone know what the stock recoil spring is is the standard shadow? Link to comment Share on other sites More sharing options...
BMaus Posted August 30, 2015 Share Posted August 30, 2015 I believe the stock main spring is 17/18 lb and the stock recoil spring is 14 lb. I would change the main spring to 13 lb and the recoil spring to 11 lb and your own choice of grips. Leave everything else standard and put 5,000 rounds through it.

Seems to be a lot of benefit to polishing the trigger bar too, but I guess 5k rounds will do the same thing. Link to comment Share on other sites More sharing options...
Timido Posted August 30, 2015 Share Posted August 30, 2015 Thanks I will test drive an 11 and 12 recoil spring. I am going to try the 11.5 pound hammer spring I already have also. So far it was 1 round fail to feed in the first 1000 rounds. 500 of them were with the 13lb main spring. All of the ammo was 115g blazer and UMC Link to comment Share on other sites More sharing options...
