  1. thats awesome! How did you time it and secure it? I just tested my 3rd attempt at fitting a comp on the 01 - Almost successful! I have the square glocky 11 port SJC comp. To time it correctly I hacked the face off and faced it down to time correctly and then used high temp locktite. It held time during the minor PF test rounds but started timing on the hotter rounds. I'll get pics up soon, I'm considering either a set screw or a through pin to keep it from rotating.
  2. Well I tried the comp and it lasted 2 mags before it started to come out of time again. It looks like I will be lapping down the threads or coming up with some shim washers. I had tried using some fine lead solder wrapped around the shoulder of the threaded barrel. It seated well and swaged flat to time it correctly. I added the red threadlocker alnong with it and tried it with minor PF rounds. Still loving the action and setup of the 01 SAO, can't wait to get this comp times and settled.
  3. That's cool. Good luck with it. I'm sure there is a powder with titanium spark suppressant somewhere...
  4. Sent 2 barrels off to be reamed to 1.160" one for my old 75B and the threaded 01 barrel. more slow progress when it gets back...
  5. There is still a gap between the comp and the barrel bushing. The gap was there when it was timed correctly and is still there. What I believe is happening is that the shoulder face of the extended threaded barrel is mating with the face of the counter bored comp, so my plan is to try lapping the face of the comp, which is about 1/2" deep into the body of the comp. I bet a .40 cal chamber reamer would do it properly. Of course the HF heat gun is toasted, so we will see this weekend. If it wont get it up to temp to ease the thread locker I have an oven and welding gloves in the garage. I don't want to play hot potato with it unless I have to. I'm debating having the chamber reamed while I'm in the middle of attempts. I still had a great time at the range. I won't clog this thread up too much with that but I got my first 10/22 and shot it and the Ruger slabside(still my fav plinker). Used chrono for the first time to data handloads and the old 75B at plenty of ammo. Updates to come. Thx for the prodding. it is fun.
  6. Well, my first try was a failure, I quit, going back to stock glocks... mmmkay.. 4 limited minor shots into testing it was out of time. I think I know why and I think I have a new plan. I think the way I sloped the profile of the relief on the comp it would still run, but be held at that point that is ~4 out of time. doesn't matter cause it will be addressed. The reason - When I dry fitted the comp it started to lock up on the threads when the comp was about 180 degrees from where it needed to be, the top vents were pointing almost straight down. When thinking about the final fit, I though about torquing it down in addition to thread sealer, but thought(what if I get 1/2 way to where the vents are pointing around 10 oclock and it locks up? Then I'm pretty fubared. I decided to unthread it 1/2 turn to time it and set the locktite. lasted 4 rounds. The possible solution - get the thing the rest of the way off, degrease and such. Then check timing. I have an idea I want to share about timing. To increase/adjust timing, there are 2 things I think could be done. 1) add thin brass washer 2) lap the face of the comp and grind it down until it times and load properly. 1) would be an easy 2nd try IF the correct washers could be suggested/linked to - can I use the same ones for muzzle break timing adjustment? I'm not good with ARs ironically. 2) this would almost be like a valve lap job. I've got all the compounds and am sure I could rig something up to provide enough force to polish it down just a bit. What do you guys think/suggest? Either way I need to get some high temp loc tite on the way. I found out that even the red locktite and red permatex are only good up to about 300 deg. but the specific high temp lock tite is good to good to 450.
  7. it's in another thread on the other fav site - https://czfirearms.us/index.php?topic=108809.msg856435#msg856435 124 PDs (my fav) over sport pistol for limited minor. 124PDs over Alliant Power Pistol for major - considering other powders. load on D650.
  8. Took some filing, but it clears - polished dog turd, but whatevs, it clears. I'm wondering if it might help to have a thin brass spacer washer to time it just right, but looks like too much trouble. It would have to be very small and fitting would be a PIA(taking washer on and off and filing between times). I'm off to get some red lock-tite in the AM and with any luck, if it's not drenched this weekend, start out with limited rounds and see how she goes.
  9. Saving someone the hassle if they want to go that route of the reverse housing /plug. Here is the best chance I could come up with in the US. It is a link where you can sign up to be notified when the part is in. Can not pay for the part beforehand, only be notified. I skipped it because of reasons below... https://shop.cz-usa.com/SearchByKeyword?word=315047000002 Since that will require milling, and a Tac Sport slide, I'm skipping that option for now. I've made just a tiny bit of progress that shows promise, I think... So I couldn't screw the comp on far enough to seat on the barrel bushing because the guide rod was just about 1/16" too long. I "clearanced" it to be just a little short. What this allowed me to do was screw the comp on the rest of the way and see what needed to be cut off the bottom corners of the SJC 11 port comp. It looks like it will fit in the frame with just a bit of simple file work. Thanks for the offer on the reverse plug, but I'll pass for now. I did also speak with a local open gunsmith and he said he uses guns with bull barrels and finer threads and locktight and sometimes set screws. --------Edit---------- I guess I'm not saving anyone any hassle if those have been out since Dec.
  10. 48 Recoil Spring Guide Casing from this diagram. https://cdn.cz-usa.com/hammer/wp-content/uploads/2014/04/75_TS_Czechmate_en_06-2012_web.pdf CZ-usa mentioned this: We do generally carry that item however it is currently out of stock. The part number is 315047000002 on our Webstore and is $50.00 before tax and shipping. I'm still a bit fuzzy on how/if the slide would need to be clearanced to use one of these. Is it a drop in and go or need milling/fitting. Has anyone threaded the end of the guiderod to accept a nub that would keep the comp from coming OOT? Just ponderings...
  11. I would think that you could either thread current fitted barrel - or buy a threaded barrel which most likely would have to be fitted. My threaded SP-01 replacement barrel did require fitting and I would not call it easy. Good luck! I've just emailed the normal places (first page results of google) and asked for in stock Czeckmate revers plug and guide rod and no on has them so far...
  12. Ronnie Jr. I'm looking at this setup now that I have threaded barrel and the same 11 port SJC comp in hand. Did this work out for you? idd you have any issues with the comp coming out of time? did you use the red threadlocker? I'm curious as to why you clearanced the frame as opposed to clearancing the comp? I'm considering just milling off the bottom corner nubs, and then take some off the mounting face so it times correctly (maybe with a thin washer or two). I WAS thinking that I could just fab some guide flats that mount to the pic rail and keep the square profile from rotating, but I had it in my head that the SJC comp had a larger "belly" section that the guide would slide on. turns out that would be a bit of a stretch though. I just got my bullets of choice and am working on some Power Pistol loads this past weekend. I can tell they are superior to what I was shooting and I'm not close to major yet. Thanks again for the insight!
  13. day late dolla dolla short... looking for this comp - as listed up there^^^ https://stores.sjcguns.com/sjc-major-9mm-11-port-aluminum-compensator/ so called SJC customs and N/A called shooters connection and they said they no longer distribute SJC so what they have is it. They have the 5 port but that's all, they do have 40 cal 11 port - pass. I'm also working on getting some machining tools and very interested in making a comp. and other parts. If there is a good book or resource on comp milling and comp design please advise. Update.. called SJC and guy answered very knowledgeable good service so I put in the order. he said they have had many of these in service useing the red locktight with no set screws. He said set screws can misalign the bore and cause baffle strikes because its so long. Working on load Dev this weekend. New custom seating stem for the 124 PDs should be in tomorrow - stuff coming together!
  14. Ahh.. more wool removed. thx. I meant to post my gun in the open poors thread as it seemed more appropriate, but it was late and stuff. I appreciate the info and will try to keep this thread clean of my noob ???s. I think I'm going with the SJC Comp. After fitting my first barrel, I'm basically married to it for a while. I saw the relief cut on the frame of an 01 with same setup, and fell better about doing that than buying a new barrel and then treading and fitting it. Thank you for the link!
  15. Whoa, its been a crazy week. I'm just catching up on this thread. Lots of good info. Ludde, that setup looks very nice. I hope it shoots well for you. Did you have to ream chamber to get maj PF? Threaded barrel got lost in mail a few weeks ago - last one CZ had - now backordered, then original package shows up 2 weeks later... I just swapped internals from old 75B SAO conv to the 01. I had been putting it off, and parts of it were bad, but not near as bad as I'd been building it up in my mind. I learned a LOT the past week. Fitted S2 ext. safety, fitted my first threaded barrel, troubleshooting reset issues etc..finding tiny springs in carpet...I thought I had a safety issue with my adj. sear, but turned out it was a broken detent spring. So... I'm looking at comps now- any suggestions throw them up. Got some questions too. Like RonnieJr.s setup - that comp is a 40, would it still be GTG with 9-I can't tell in his pics if he is shooting 40. Comp suggestions Goodish/cheapish please - I'm good up to about $150 ish since I saved $$$ scavenging parts. I don't really care about looks, more function. Will/would PCC comps work OKish with this build- looks like most of these have large side ports which wouldn't be good. Can I just thread it on, time it with shims and try it out. I'm not opposed to the set screw and red locktite, but I want to make sure that all the other bits are GTG before it is locked.
  16. Ok, I'm on this train now. I've been lurking for a while. I just sold and S2, got my SP-01 safety model back so I have $$$ to build it now. The SA just didn't compare to my SAO gun, I have minimal interest in DA/SA. I thought about building up my 75B limited, but the beavertail on the 01 just feels so much mo bettah and that was the ultimately the deciding factor... about to order a threaded barrel and comp. Really like the long square comp, where did you get that one? After that SAO/Race Hammer, springs and magwell. Sights/optic will be last.
  17. If that barrel is longer than standard I'd be interested in it. I'm looking to put a comp on a standard 75B.
  18. Those Dawson adjustable look good. I originally wanted the three dot for accurate shooting, but found in stages, the solid black rear is better for me. My eyes tend to 'waste time' trying to line up the shot with the 3 dot. I had many people tell me this and I did not believe it until I got to a stage.
  19. How long is that barrel that is .501?
  20. I've left rounds in the car on the dash before, that works great. If you are into any types of powder coating, you can get a used toaster over. They go up to 400 deg, vs the dehydrator for the same price. they might not have the same capacity though. I toast mine at about 150-200 degrees for 30 mins if I want them now.
  21. I'd say box it all up into a type of throne or whatnot, then sit on it and mope until the wife asks what's wrong. Dillons get 80% resale. The new 750 is out and some people are looking for 650s because they don't like the new priming system. Honestly I'd run a bunch of ammo if you can, then sell it off and upgrade to M7 later on if you jump back into it. Or sell it to a friend with the stipulation you can use it when needed and buy it back. Like having a friend with a boat. Keeping the SS is a no brainer, as good quality rifle rounds are money and the SS takes up much less space than the Dillon.
  22. I'm trying to jump into open major from limited. Shooting a cajunized SAO 75B 9mm. Threaded 75B barrels are out of stock, I'm considering just buying a 6" barrel and threading the end for a comp (poors/quick/dirty). Would there be a distinct advantage to leaving it 6" or cut down to 5" then thread? IDC about sight radius as will D/T for optic. Understood that draw and transitions would be affected, I'm mostly wanting to see if the longer barrel will allow lower pressures while still making major. I don't care about looks because people look at me and my gun in a funny way already.
  23. Yes, thank you, I swear I'd come across that sometime last year, but couldn't find it since. It doesn't turn up in a search for "Sights" So now its between that one and this non adjustable one - It would need a taller front post but I might be able to make that work for me. https://czcustom.com/cz-parts-all/front-and-rear-sights/cz-rear-sights-all/cz-75-competition-rear-sight-standard-dovetail.html
  24. Looking for options/opinions on the best rear sight for competition: Gun is old 75B SAO limited minor with standard sight height FO front blade. CZCustoms has one for $45 that uses the standard front sight height Dawson precision has some, but I don't see just the rear sight. Adjustable ones would be cool, but looks like they need taller fronts, also worried about them coming loose. Budget minded option will most likely win - any money left on the table will obviously be spent on other gun stuff in the queue.
  25. After reading the article at this link a while back -https://www.dropbox.com/s/mmk8tv8yrk7vii7/12.23.15-Dillon-Prometheus-Article.pdf?dl=0 it really opened my eyes as to the ability of the 550 - I run a 650, but I think a lot of what is in that article could be done on the 650 as well. I haven't ventured down that road yet but might later this season. I will still be weighting out charges on a separate powder drop though. Note that they are sizing and loading in one process/toolhead. I would think that the possibility of sizing and loading in one run would be determined somewhat by bolt or gas. Gas needing more sizing, which means more case stretching, which means more trimming.
