Best Hammer for Shadow 2 SAO

[AZ_GunGuy]

I've already removed the disconnector and replaced the factory trigger with an SAO one.  So far I've looked at CZ Custom and Cajun Gun Works.  I'm thinking about trying this one:

That’s what I use on my shadow 2’s. I think it aesthetically looks more correct than the Cajun race hammer (which is a great hammer). I’m just not a fan of having to fill the gap with the spacer for it.

Absolutely nothing wrong with stock hammer.  The gun will go bang every time you pull the trigger if there is a live round.

Not sure why with SAO you want a new hammer, however I have this one in my two Shadow 2s:

The main reason is I like the larger hammer for decocking at the start of the run. Does improve performance of the gun? Nope, just easier to manage for DA start. Since you are set up for SAO it doesn't really matter.

I've seen videos were people claim the competition hammers reduce creep and have a cleaner break.  They claim the geometry is a bit different than the factory hammer where the hammer meets the sear.

 

I'm also interested to see if it affects the SAO trigger pull weight.  From the responses so far, it would appear not.  I'll test with a Lyman guage before and after the upgrade.

GunGuy, please report back with your findings after you make the change. Inquiring minds want to know!

Thanks

Claiming and accutally doing are two completely different things.  They may well be as claimed, and just as easily it may be an assertion not based in fact.  For the 0.5-1.0% of competitors that actually need the absolute best hardware and $ can provide it may will be worth it.  For the remaining 99.0-99.5% of us.  We'll never really see it.  My opinion obviously.  It you firearm and $, and as such, certainly upto you on what and how to do it.  Hope the mod is worth it.

To answer your question. The competition hammer reduces creep in SA. It’s still slightly present but improved from the stock DA/SA hammer.

I installed the new hammer today.  I had also previously installed a CGW reduced weight trigger return spring and the CGW ultra light kit.  Also my Shadow 2 has an Eemann SAO trigger and the disconnector is removed.  Currently running a 11.5lb hammer spring.

 

Lyman results with stock hammer:

2lb 2oz

 

Lyman results with comp hammer:

2lb 3oz

 

Not sure if this is a break in issue, but the trigger pull is slightly heavier.

 

However, the creep is down about 50%.  This is a bit subjective, but I really feel it's way better than with the stock hammer. Looking at where the hammer meets the sear cage, the geometry is definitely different. 

 

I think this result can be validated by observing the over travel screw.  I put the screw in using blue loctite and calibrated to the stock hammer.  There is a larger gap now after the break.  Enough room that I need to adjust the screw - meaning the trigger actually breaks slightly earlier in the pull. 

 

So in conclusion, it's not the first upgrade I'd recommend, but if you're wanting to reduce creep I think you'll be happy with it.

Small update, trigger pull is back down to 2lb 2oz after some oil and dry fire.  Very happy with the comp hammer.
