    Help, trigger can't be pulled or hammer cocked!

    in CZ

    Posted · Edited by Brucenterry

    I'm hoping someone here can help w/ my SP-01 tactical w/ CGW carry package installed (2 yrs ago).  Headed out for a range session today and dryfired a few times prior to loading a mag. Then I tried to rack the slide and it wouldn't.  I was able to move it enough to remove the slide from the frame but still can't pull the trigger or operate the hammer.  I'm not seeing anything obvious.  What shoud I be inspecting? 

     

    Thank you in advance,

    Yes, I noticed it just the other day.  A fellow shooter also commented that it is hotter (higher pressure because of the alum. case?) than other brands but that's good if your training....it's closer to a carry round so recoils is more similar.  I had no trouble running it thru 2 glock 19's and CZ clone and at $8/ box it's affordable.

    How to make 9mm reloads equal factory?

    I think I read somewhere that if the bullet is truly tumbling, your velocity may be too low for your barrel.  Try upping the powder charge (using a Chrono) to see if that helps.  Also be sure to have cardboard behind the target to support the paper or the holes will look like a tumbling bullet.  The best luck I've had so far is w/ SNS 135g coated behind 3.8g of N320 at 1.135 in a CZ.

    Good luck.

    You may try swapping barrels to see if it follows the gun.  Only other difference is the recoil spring.  I have a gen4 that does this.  Had several people shoot it and tried several brands of ammo but still the same results (high left).  Swapped barrels and it improved so I bought a KKM barrel but still not as good as my gen3's.

    I'm running the 11# spring as well.  I've installed all Cajun production legal parts including that spring.  Nothing wrong w/ HP38 (W231 same powder), I only started w/ it because I'm new to reloading and folks recommended it as a good universal powder and it would be hard to double charge based on volume required.  I only switched because I heard such good things about N320 and ran across it locally (no hazmat fee) so I gave it a try.  I do like how N320 meters on my Dillon 550 sq. deal! 

    Once you work up some loads, test for velocity vs. accuracy.  I think you'll find that IDescribe was right on the money.  You'll probably get the best accuracy ~137ish PF.  You can go lighter, but I don't know that you'll really be able to tell a difference in felt recoil so why not be as accurate as possible.

    Good luck!

    Mike, I just went thru this exercise w/ an SP-01.  My barrel my be slower down here in Cincy vs. Cleveland (lol), but it required 4.0g of HP38 to get good groupings. I've since switched to 3.8g to VV N320 (just a tad hotter) because I feel it meters more accurately.  Like IDescribe indicated, target a higher PF, CZ's like faster rounds to be accurate.  My most accurate load has a 137PF at 1.13 OAL behind 135g SNS bullets.

    Fed Std Primer

    Thanks Taroman, 3.8g's got me to your numbers exactly out of a CZ, just wondering how much is too much!  I ran 3.7, 3.8 and 3.9g.  3.9 felt/shot the best, not sure if I should try going hotter to see if accuracy improves or do you base the best load on min ES/StDev?

    If Federal is #1, what's your #2?

    Not to hijack the thread, but I was looking here for primer recommendations since I just ordered a Dillion 550.  I'm using the OP's setup in SP01 decocker w/ a CGW Pro Package.  I could use suggestions on powder and bullets brands and sources if allowed.  Currently shooting 115g and in my first match and had 3 lite strikes w/ factory Aguila ammo.  At first I thought I short stroked the trigger, but afterwards remembered it was DA on second pull.

    Thanks in advance.

    Biglou13...Yes, I have the 13# hammer spring that came w/ the Pro package.  Maybe I'll try the 1200 (11.5#) to see if I get light strikes. 

    bowenbuilt....what adjustments need to be done to the trigger bar?

    Thanks for everyone's input on tuning a CZ.  I bought an SP01 (w/ D'Cocker) after shooting a friends who had it worked on by CGW. I called CGW and they recommended the Pro-Package since I want to shoot Production.  After reading and watching video's, I've successfully polished and installed all the parts.  I don't have a trigger pull gauge, but I'm extremely pleased w/ the SA pull weight but wish I could get the DA just a little lower.  I know going too low on DA can cause light primer strikes but what can I polish/replace to reduce the DA weight a little more?

    Thanks in advance,

    Fiber Optic Front/Rear Sight

    in CZ

    Posted

    I bought a SP-01 Tactical for USPSA and would like to change out the stock sights. I've been using TruGlo Fiber Optic sights on my Glock and like that set-up but they don't make them for CZ's. Also not sure if I will like the blacked out comp rear. Does anyone offer Fiber Optic front and rears that will fit my gun?

    Thanks in advance,

    G17 gen Accuracy

    in Glock

    Posted

    I need some direction. I have a gen 4 G17 that has poor accuracy. During a trading class, I had a nationally recognized pistol shooter confirm this using 4 different types of ammo. It shoots ~6" high left at 15 ft. I suspected the barrel, but a KKM barrel made no improvement. What else can I try. The locking block appears different from my gen2/3 so don't think I can switch those.

    Thanks in Advance,

    Hello, Newbie from Ohio

    Hello all! I ran across this sight and am enjoying all the useful information. I started using it for FN-S info, but after shooting a friends tricked our CZ SP-01 Tactical race gun, I bought one myself. There's so much good info, I'm going to attempt a serious CZ trigger job per all the helpful instructions. I'm a little concerned since most of the articles are for the "safety" model, but I'll mutter thru it somehow.

    Wish me luck!

    Regards,
