Brucenterry

It's the decocker version.

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, Bruce

I have a 1K of SNS 135G I want to load for the X5. Do you have any load data on the bullet weight? If so....any thoughts on accuracy w/ same bullet weight? Thanks in advance,Bruce

I asked Country Attic if they could order some, and they found it listed in the Aliant catalogue, but their min. order is 10#'s. Unless they have other requests...I don't think this will happen since they'd never heard of it.

For anyone interested, Country Attic has N320 in stock (2lbs) as of Saturday afternoon. They have almost all Allaint powder too but no Sport Pistol. Have a great weekend. Bruce

Thanks Ken, I asked them to order some and they said they'd call me when it's in. I'll let you know if that happens.

Thanks Sarge, that's where I usually go but they're out of N320.

Where do folks in Cincinnati locally purchase your powders? Thanks in advance, Bruce

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.

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.

Thanks everyone! This helps tremendously.

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?

Vihtavuori doesn't list data for N320 and 135g coated lead that I can find. Anyone know what the max loads so I don't get into pressure trouble? OAL is 1.131. Thanks in advance for your help.

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. Bruce

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, Bruce

Thanks everyone for the suggestions...I went w/ the Dawson FO's. Hope to put them on this weekend.

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, Bruce

Thanks 9X45 and Hbb I'll research those suggestions. Regards, Bruce

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, Bruce

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,
