CZ SP-01 Shadow - crazy quest for a 4 lb trigger

[beanz2]

So my wife is really into handgun classes at Front Sight, but rumors have it that they're going hard line and enforce their silly 4 lb trigger pull weight minimum. Some students have been using factory-stock guns to pass the first-day weapons inspection and later substitute gussied up guns for the class. Now guys in the FS training thread are saying FS staff will make surprise visits to ranges and check everyone's triggers and, if you are found to have a trigger much lighter than 4 lbs, they will throw you out and blacklist you from the school.

Well, our guns have very light triggers. My wife's SP-01 Shadow has a 2.3 to 2.5 lb SA trigger pulls. Even Rob at CZC says stock SP-01 Shadows have 3.5 lb triggers.

Now the wife wants me to get her trigger to 4 lbs I found the parts needed at CZC so, it's only a matter of throwing money and time at it.

Is it possible to have a buttery smooth 4 lb trigger on a hinged trigger like on the CZ? My Dan Wesson PM9 has a very nice 4 lb trigger but it has a sliding 1911 trigger. She'd use that for classes if it wasn't for the 8 round capacity.

Looking forward to the DWX, but there is no guarantee it will have a > 4 lbs trigger.

Hinged triggers rely on torque - force x distance.

To increase the pull weight move the gauge closer to the pivot point. Less distance requires more force to pull. Simple

Why the 4# rule: Too many negligent discharges?

Some Beretta 92 competition guns have nice triggers, but I do not know if they are considered buttery smooth.

Problem is, the staff are the ones doing the trigger weight checks, not the students. Yes, pull higher and pull at an angle, that'll raise the weight

Not sure why the 4 lbs rule. I'm sure it was something legally related. Maybe for beginners classes, not for all of them.

Last October they would not allow my Shadow 2 which has a 5# DA and a 2.75# SA. I also had my EDC which has a 4.5 # trigger and it passed. When I got to the range I used the Shadow 2 anyway...

CZ SP-01 Shadow - crazy quest for a 4 lb trigger

My stock CZ SP-01 was smooth and I believe it was heavier than 4 lb.

What I did was only polished the sear and hammer engagement.

Sounds like a reason to get a new gun! Keep things familiar and get the Cali sp01. I’d do that before trying to make a kick *** shadow to make weight for training.

LOL. Having a house 40 minutes away and not use our lifetime membership to Front Sight? We go to other schools too for variety.

I was reading you can also use a witness sear spring to make the trigger pull heavier. https://benstoegerproshop.com/eaa-ta...ar-spring-9-3/

You got me man
I knew how to polish the moving parts, I know how to deburr the hammer, I knew how to sand/stone the sears. But I do not know how to un-polish, put the burr back and add the metal back to the sears. You got me man I knew how to go from 4# to 3# , but I do not know how to go from 3# to 4#, You got me man

Thanks. Interesting. This is to go on the CZ's sear, right?
Picture of the part railroader is referring to:


I was thinking of CZ Custom's Carry/Duty Hammer:


and their Heavy Trigger Return Spring:


Wonder what trigger weight does Cajun's Defensive Carry Package if combined with CZC's Heavy Trigger Return Spring gives? With their provided TRS, the SA is 3 lbs 8 oz.

On the sear spring I just did a search and using that sear spring came up as working to make the trigger pull heavier. I think if you change the hammer you might have issues with your safety working correctly with your stock sear since it's fitted for the shadow hammer. I put a CZC hammer in a 75Bsao and I had to adjust the sear arm because the safety wouldn't work. I guess you could always use a CGW adjustable sear if you need too.

+1 Why spend several hundred dollars only to be treated like a jerk? No thanks, Front Sight.
