jbinpa59 Posted February 18, 2018 Share Posted February 18, 2018 (edited) OK thinking about drinking the open koolaid Primary intended purpose is 2-3 local club level outlaw steel matches per year to see how bad the bug bites so not wanting the investment of a chechmate. I prefer cz style frames I've got kimber/para /auto ordanace so I know the difference in feel of cz compared to 1911/2011's I know I can load longer in large frames giving more powder choices for 9major I've read all the cz open threads I could find. CZ's I currently have in hand are; TacSport in 40s&w for Limited major plus a complete 9mm upper for minor/plinking SP-01 9mm set up for production SP-01 9mm with vortex viper on a dovetail mount for CO which is mainly what I shoot now ( I plan to get the slide milled ) 75B 9mm loaner,plinker, $350 project base, gun bought used excellent other than a slightly pimpy color scheme stock internals Prefer to make as few permanent mods as possible at this time to SP-01,s Willing to mod the 75B My proposal: Buy CZ USA threaded barrel in 9mm (I know the 1/2-28 threads limit comp choices) Glock compensator or ??? Open to suggestions not sure I want to cone comp slides tho Steel extended guide rod as locator/lock for comp? Should total $350-400ish?? For steel my existing mags collection is gtg If I go to open I'd need 3-4 140mm and 1-2 170mm basepad /spring setups to add to current mags ~$250ish Slide? Use the SP-01 CO slide /vortex combo? Already has clearance hole for guide rod Or the 75B slide with a dovetail mount for now? Adds $230 vortex plus needs drilled for guide rod Frame choice? If I use an SP-01 frame may be heavier. but already has some cgw parts/polishing 75B frame should be lighter, but totally stock internally so would need some parts and polish work Or just go for it and drill the 75 frame for the guide rod and a frame mount and jump in the deep end Which I can do on a Buddy's Bridgeport Add about $100 for mount and I'd need the second vortex anyway using the 75B slide $50 for another data racer block $300-350 in tune up parts and kneeling atlas's tuning guide Might manage to do a 75B based full build for $1350-1400 plus the 75b in hand? Which is what I'm leaning towards doing Or a steel oriented poor boy open cz for a $400-500 outlay by Lego blocking a frame/co slide/barrel-comp setup??

aandabooks Posted February 18, 2018 Share Posted February 18, 2018 75SA on a TS frame. You should be able to do the same with a SP01 upper. Link to comment Share on other sites More sharing options...

OrondoShooter Posted February 18, 2018 Share Posted February 18, 2018 You and me both, kid. I carry a P-01 frame with a SP-01 slide milled out for a DPP. My only problem is the comp. I disn't exactly know if a M&P comp would match the contour of the CZ without a lot of work (dremeling). So I'm going to get an extended SP-01 barrel, cut it down and thread for m14x.075, put a tanfoglio small frame comp on it, and mill the comp for side ports. Glocks are really wide, and frankly, I'm not sure anything but a G43 comp would work without taking it to the mill so it'll fit inside the frame when it cycles for yah.

dogtired Posted March 9, 2018 Share Posted March 9, 2018 I screwed a SJC glock comp on my Witness open gun. The size is reasonable. Beauty not so much. Link to comment Share on other sites More sharing options...
MikeBurgess Posted March 9, 2018 Share Posted March 9, 2018 the 170 mags will be the biggest hang up in a 75 based open gun. you can weld some up or buy the Tanfoglio small frame 25 rouders and put different guts in them. The Tanfoglio mag is $150 when you can find one in stock, I haven't changed the guts in mine yet so I'm not sure what they will hold, also they have a plain base pad like a stock mag. I have seen pictures of aftermarket bases for them but I believe those would have to be ordered from Europe. For a bigger budget the PT evo grip for 2011s feels a lot like a CZ frame, also the czech mate is an option. Link to comment Share on other sites More sharing options...

Jody Waring Posted March 11, 2018 Share Posted March 11, 2018 Would a Czechmate comp match up with an SPO1 threaded barrel? I have an open gun built on a Shadow but I am not sure what the smith used for a thread,... He built the comp and fitted it to stock barrel.

The Czechmate comp can be threaded on to an SP01 barrel, but the cone on the CM comp is smaller than the OD of the SP01 barrel bushing. Link to comment Share on other sites More sharing options...

I had assumed something like that would be the case. I wonder if CZ Custom will ever offer a barrel and comp kit. Even if not used for major power factor, it would make for a nice steel gun, 3-gun pistol etc... Or minor power factor IPSC for anyone opting to do so. I plan to use mine for steel challenge and Pro-Am type matches. Link to comment Share on other sites More sharing options...
kneelingatlas Posted March 12, 2018 Share Posted March 12, 2018 The Bull Shadow slide would be perfect for that since you could pull the barrel/comp out the front of the slide in one piece like a 2011 Open gun. Link to comment Share on other sites More sharing options...
TSL Posted April 20, 2018 Share Posted April 20, 2018 (edited) It’s a TS .40 ported it’s great just don’t go crazy putting too many holes or you won’t have enough pressure to control muscle rise. Edited April 21, 2018 by TSL Link to comment Share on other sites More sharing options...

TSL Posted April 21, 2018 Share Posted April 21, 2018 Thanks! It’s IPSC Alex Thumb Rest. The holes in the thumb rest actually lines up with the scope mount and after measuring my grip/hand that’s where we need to mount it. Link to comment Share on other sites More sharing options...
George16 Posted April 21, 2018 Share Posted April 21, 2018 That’s a better thumb rest compared to the stock TSO thumb rest which I have currently mounted on my gun. The stock thumb rest pad is too small. Link to comment Share on other sites More sharing options...
TSL Posted April 21, 2018 Share Posted April 21, 2018 (edited) That IPSC thumb rest is huge.. Cool gun! Nice to see we have similar set-up Edited April 21, 2018 by TSL pic error Link to comment Share on other sites More sharing options...

Greengun Posted April 21, 2018 Share Posted April 21, 2018 TSL, May I ask the hole measurements on the barrel and slide and how does it work for you? Link to comment Share on other sites More sharing options...
George16 Posted April 21, 2018 Share Posted April 21, 2018 (edited) If the CZC mount(which looks like it) TSL used is the same mount I used for my TSO, then the hole pattern is the stock TSO/CM mounting holes pattern. The holes themselves use M4 screws. Edited April 21, 2018 by George16 Link to comment Share on other sites More sharing options...
Greengun Posted April 21, 2018 Share Posted April 21, 2018 Sorry, I meant to say the port at the muzzle on the barrel through the slide. Not sure how to call it. Link to comment Share on other sites More sharing options...

Hi, if your asking about the scope mount George 16 is correct but if it’s about the port holes.. in my opinion just go straight with MagNaPort. Just let them do standard autoporting. That’s what I have. How does it work for me... it has a significant difference and in all honesty every penny is worth it. Before I sent my upper to MagNaport I did a few basic test, double tap as fast as I can and see the pattern. When I got the slide back I did the same test.. second shot is a lot lower now. So from 13lbs recoil spring I went with 10lbs. to level the POI and using lower recoil spring it felt a lot smoother.

George16 Posted April 21, 2018 Share Posted April 21, 2018 TSL, what loads are you using? I’m currently using 124 Gr FMJ with 4.1 Gr Winchester 231 and felt recoil is very minimal. Gun shoots flat and I’m using a 10# CGW recoil spring. Link to comment Share on other sites More sharing options...
TSL Posted April 21, 2018 Share Posted April 21, 2018 (edited) Hi George, mine is a .40 I’m using Missouri 140gr lead and LongShot powder.. still working on my loads atm. Edited April 22, 2018 by TSL Link to comment Share on other sites More sharing options...
