I was at the range the other day with a few CZ’s testing out my reloads. There is this Steel Challenge stage called Pendulum where it has two 10 inch diameter plates at 18 yards. So I was using a matte stainless CZ-75 in 9mm and a SP-01. Both are DA/SA. There is a lot of travel or movement in both triggers before the hammer drops. Attached File Attached File I know there are a few CZ models that are single action only. I am ASSuming there is way less creep / travel / movement in those triggers. In your experience, do you think that would yield better accuracy results at 18 yards? |

DA should only be your first shot. If they are stock internals, if you are compitent enough in your gunsmithing skills you can lower the hammer hooks to take out some of that creep in the trigger. If they have firing pin blocks then there is only so much you can do about reset length. Polishing up the trigger bar and pins is free. There is alot that can be done without sinking the coin into a full trigger kit upgrade from Cajun Gun works. Are those braced groups off a bench or standing up shooting free hand? If I am braced on a table, my CZs will shoot 1" groups at 20 yds with my reloads. |

| I got away from CFE pistol and found Win244. It has been the best shooting powder in my CZs innthe 124-125 range of jacketed bullets. I use RMR 124 match winners and 4-4.1 grs of Win244. Right around 1050 fps and super accurate. CFE seems to slow and blasty for me. Would work good on a comped gun though. |

I went with CFE pistol because it was bulkier. I figured it might produce enough gas to work the comp. This would be at minor Power Factor. I was hoping just to crank out one 9mm load in bulk and use it across multiple “platforms” I tried my hand at powder coating some lead boolits that I casted. At 7 yards, they seemed alright: Attached File But then I pushed them out to 18 yards: Attached File Uggg…  |

Ya “dun” talked me into it. I bought an 8 pounder of Winchester 244. I went to the Grand down in Sparta, IL today. There is one regular vendor there selling reloading components to all the trap shooters. So at the bottom of his grease board, he had Win 244 listed. There was another vendor there who had an 8 pounder of Bullseye. I was almost ready to buy it but, but my card was partially melted as it was.  |

Have been wanting to try it in 45 but don't want to spread it too far across my calibers. Well…just as an FYI, it is…err…was Mike Graf’s booth yesterday at the Grand. The crew from Full Circle Reloading in St. Charles, MO is taking over, at the Grand. Mike is going to retire-retire. He was just there as like a consultant / advisor. So chances are if you are in the St. Charles, MO area, swing by Full Circle and they will probably have Winchester 244 in stock. Since I paid with a card yesterday, they tacked on 3%. I want to say it was $334 and some change out the door. |

Come to find out, I have twice that in HP-38, which everyone says is the same thing as Winchester 231. EDIT: I have not shot a .22LR in years. All mine are conversion kits, not dedicated .22’s. But you do make a good point. |

SaO is the best kept secret in CZs. It’s pretty easy to do. Lose the disconnector and install sao trigger shoe. Sao trigger shoes come in all shapes and sizes with over travel and pre travel set screws. You no longer have to mess with ghetto extended firing pins or underpowered springs or light primers . All that is for cleaning up a now non existent da pull. Ditch the firing pin safety parts if present. CGW has the spacer. Upgrade hammer and sear for the cleanest possible pull. There are all manner of aftermarket extended safeties. They discontinued SAO shadow 2 right before limited optics took off. People gravities towards TS2/3 for that but back in the day they were a grand and had a stock crisp 2lb trigger. |

About a week or two weeks ago, somebody on another forum was selling their TSO. It is in .40 cal. And hardly anybody shoots USPSA Limited any more, so not a lot of people shooting .40 at matches. Which reminds me…I really do need to tear down my Czechmate to give it a good cleaning. I think the other 3 CZ’s I have are all DA/SA. |

It's really not too difficult to make a DA/SA CZ into a SAO pistol. Take the pistol you've got and remove the hammer so you can drive out the pin holding the disconnector to it and then you can reinstall it without the disconnector. Or buy a better hammer and install it on the mainspring strut. That'll help clean up the trigger pull a lot. An adjustable sear from CGW is the way to go vs. modifying the thumb safety lobe for the new hammer. BTDT. I think it took me around 20 tries to get the safety lobe on the safety lever shaft just right when I put the spur hammer in my CZ75 Compact. When I did the CZ75B .40 I just used a CGW adjustable sear and it was right the first time. The adjustment of the pre travel and after travel screws is also a bit touchy getting them just right. You need a little bit more than "it works" or you can get into slight wear/dirt/heat issues at some point where the trigger won't move the sear enough to release the hammer. I did, on one pistol, have to modify the SA (straight) trigger. I had to remove some material from the front upper section of the trigger so it would move forward far enough to reset the firing pin block parts. It acted normal as could be dry firing at the house but would not fire at the range. There's a reason why the people that sell gun parts always say you should have a qualified gunsmith install your new parts. Sometimes you run into funny little things on one pistol you don't see with another one. Some CZ's come out of the box good shooting pistols. Some need a bit of help. The one, a metal framed P01 (with the ambidextrous thumb safeties) got a new hammer (CZ Custom I think, but it's been a few years), the disconnector removed, a SA trigger and maybe, can't remember for sure, a CGW barrel bushing). The load is compressed charge of Blue Dot powder under a Precision Delta 115 grain hollow point. A load that all the CZ 9's like and even my M&P Shields and Shield Plus pistols. Five shots, offhand, 10&1/4 yds. I think the one not in the hole with the other four was shot number 4. Attached File |
