optimator Posted April 3, 2017 Share Posted April 3, 2017 I bought a new SP-01 safety model. This will be replacing my M&P 9 pro for 3 gun. When converting to SAO, is it all in the trigger or do I need to change the hammer too? I'm also going to remove the FPB if this makes a difference. For those of you who have built these guns, what all did you do? Link to comment Share on other sites More sharing options...
clw42 Posted April 3, 2017 Share Posted April 3, 2017 You should remove the disconnector as well. Link to comment Share on other sites More sharing options...
je85 Posted April 3, 2017 Share Posted April 3, 2017 (edited) I installed a czc flat trigger and hammer in mine. The hammer made a huge difference in SA. CGW has a hammer that is great also. The stock hammer has taller hooks. If you keep the stock hammer you will need to remove the DA disconnector. Or simply not install it on the new hammer. Removing the FPB will allow you to get a shorter reset close to 1911 territory. Polish the trigger bar too. I would get a CGW trigger pin and reduced trigger spring also Edited April 3, 2017 by je85 Link to comment Share on other sites More sharing options...

I've thought about it, but that pretty much makes the CZC short disco I bought a waste. Link to comment Share on other sites More sharing options...
NoKimberDave Posted April 3, 2017 Share Posted April 3, 2017 I love it. I did it to a CZ75B. I have used it for 2gun, 3gun, and many other matches. Probably over 40-50G thru the gun. I've own two CZ's now and both are SA guns. Short disco would probably be easy to get rid of on here. Link to comment Share on other sites More sharing options...
clw42 Posted April 3, 2017 Share Posted April 3, 2017 So just to be clear, I can keep my stock trigger for now to see if I like it in SAO and then swap to a flat one later if I want? Link to comment Share on other sites More sharing options...

I have a Type 1 Disco on my SAO CZ75 SA. It helped reduced the pre travel a tiny amount. I prefer using that over the pre travel screw. Link to comment Share on other sites More sharing options...

himurax13 Posted April 3, 2017 Share Posted April 3, 2017 I am using a Grauffel Xtreme Semi-Flat SA trigger on my SAO Match Elites. However, I think if you use the OEM triggers on the Stock 2 with a BOLO Disconnector, you would have a shorter length of pull and less pre-travel.

optimator Posted April 3, 2017 Author Share Posted April 3, 2017 Thanks for all the replies. It looks like I'm going the right direction with this pistol. After watching a few youtube videos, it doesn't seem nearly as rough as I thought it would be. Link to comment Share on other sites More sharing options...
kyojin Posted April 3, 2017 Share Posted April 3, 2017 I just did this exact thing to mine. CZC Flat trigger and CGW hammer. Works great. Did this for 3 Gun competition as well. Link to comment Share on other sites More sharing options...

Those are Dawson Precision Competition sights. They seem rather small for a comp sight though. Makes me wonder if I got the right ones from them. My friend ordered some from them as well and they are exactly like mine. Link to comment Share on other sites More sharing options...
NoKimberDave Posted April 4, 2017 Share Posted April 4, 2017 One thing I like about going SAO is that the hammer spring doesn't have a ton of affect on the trigger pull. So you can use heavier springs than you would for a DA pistol. So my guns set off any primers and will run any ammo. Very very reliably. In fact, I can't remeber the last time I had a failure on either CZ. Link to comment Share on other sites More sharing options...

To those guys that run light loads, what recoil spring are you using? My 3 gun loads are around 920 fps, around 125 PF if I recall. Link to comment Share on other sites More sharing options...

NoKimberDave Posted April 4, 2017 Share Posted April 4, 2017 (edited) 2 hours ago, fastlane604 said: What happens if the disco is not removed? Good question. I believe it has to clear the FPB to reset the trigger, like in a CZ75SA, thereby increasing reset distance a bit, or if the FPB is removed, I imagine it does nothing. I am sure there's someone here with a better understanding of it. I ditched mine in the first week along with the FPB as I wanted the best trigger and shortest reset I could get. I have almost zero knowledge of the FPB/Disco/and DA as I have never had to deal with it like the production shooters do. Shadows don't have the FPB from what I understand.

The CZUB flat trigger does not allow the trigger to move far enough forward to reset to double action. Link to comment Share on other sites More sharing options...
optimator Posted April 5, 2017 Author Share Posted April 5, 2017 When I emailed CGW about the parts I need to convert my gun, I was told to remove the disconnector. Here is the text of the email I received. Hello and thanks for contacting us. For the SAO conversion without a FPB system, then these are the parts needed: 6SAO Race or Ring Hammer kit with sear (same performance, just a different shape) H-PIN TR-PIN RP-TRS S-Spacer and remove the factory disconnector, lifter arm, L-spring, plunger and it's spring Please let me know if you have any other questions: I ordered my parts last night and received a shipping conformation today. Good place to deal with. Link to comment Share on other sites More sharing options...
