Need to increase trigger pull on TS2

[rsvedell]

After 1000 rounds through my TS2, my trigger pull is now less than a pound and is very uncomfortable for this old man.

How can I increase the trigger pull to somewhere around 3 pounds.

Any suggestions greatly appreciated.  Thanks

Get a couple of heavier hammer springs and try 'em out. I think CGW, CZ Custom, or perhaps CZ-USA sell them.

Thanks. Already on waiting list at CGW.

I went through this on my TSO's.  The issue is the competition hammer does not have a pronounced wall before the break. 

You can add a 26lb hammer spring and gain about 1/4 lb.  I use Wolff gun springs in my TSO.  They come with a heavier firing pin spring to counteract the heavier hammer spring.

You can add a tangfolio sear spring and gain about 1/5 lb.

You can modify the sear to accept two sear springs and get a significant bump in trigger pull weight (unsure how much since I haven't done this).

You can add a CGW TS hammer kit and gain about a 1/3 lb.  This really improves the feel of the trigger and provides a more pronounced wall before the break, all the while making it more crisp believe it or not.

Wouldn't it be better to send it back to CZ
 stating that the trigger is too dangerous to be
used in any safe manner.

I have done this on 2 TS. The added weight is between 14 oz to 18 oz (1 lb give or take), and I believe this is the most effective way, although needs some work.

What modification needs to be done to the sear cage?

[midaltantic44]

CZ parts in Europe sells three variety of sear springs specifically designed to increase trigger pull...7mm, 7.5m, and 8mm diameters.

Not cheap, with shipping, but hey...only a box or two of 9mm ammo

Only rhe sear, not the sear cage.
The sear has to opened up to increase internal width so that it can accomodate 2 sear springs instead of one sear spring.
The original sear spring's leg locks in the notch on safety rod that pushes from edge to edge of frame, and also holds the entire sear cage in place (the left side safety). The 2nd sear stays snug towards the right sidenof the sear (when looking from rear of frame to front)in the open space created for it, its leg also rests on top of safety rod extending from edge to edge of frame.

With 2 springs instead of one, you get significantly more increase in trigger weight than you could achieve by using higher weight sear, trigger, or hammer springs.
Plus, this has no impact on recoil impulse or cycling that one could get with heavier hammer spring.

So I ordered two sear springs, 7.5 and 8mm. the stock is 6mm.

the 8 was too much, and created a sharp jerk. The 7.5, which by my caliper was 7mm, was much better, and gives me a trigger pull of 2 to 2.5 lbs. (the wheeler gauge is not precise)

that feels pretty good, light, but not too light.

FYI I also have a Cajun adjustable sear and hammer, which they say increases the pull by .5 lbs. but it is also snappier than stock.

I wonder that if with stock hammer the 8mm spring would offer a smoother pull.

This is one reason why I steer everyone who will listen to me into a shadow 2 SA as they come with a very nice 2-2.5lb trigger with wall and reasonably crisp break.
Plus you can:
1) install a +10% Trigger return spring which ensures it wont break (thicker spring) and adds ~1/2lb but gives a more forceful reset
2) install a 20 or >20lb hammer spring which will midly increase the trigger pull again (1/2lb tops).  Advantage: will set off anything, including 22lr in your kadet kit (stock shadow2 are like 14lb and do not set off 22lr).

what very little creep there was at 2lb really seems to disappear completely at 2.5-3lb.

Plus (IMO) the balance is better on the S2 and the mags are more common, cheaper, and dependable (the TS2 was made for .40, so 9mm mags have to have a rib on them, which presents problems when adding extended mag bases).  Plus the plethora of S2 parts and accessories.  (plus the aforementioned availability of a 22lr slide for these guys).

And, of course, they are dirt cheap (being discontinued too).

Hey so I have a ts2 with a the adjustable cgw sear and hammer kit.  My trigger pull actually went down  from 1# 14oz to 1# 4oz.  I was looking into the zendl springs you got, how much was your trigger pull with stock spring? And how much did the zendl 7.5mm add?  I don’t want to go into the 2# range but wouldn’t mind being in the 1# 8oz to 1# 14oz range.

Hi,
     "the 8 was too much, and created a sharp jerk."
What do you mean by a sharp jerk?
Thanks,
