TSO 40SW Rear Sight

[cheby]

Just broke the second one. The first one  - after 11K, the second  - after 8.5K. So should I replace it before every major match from now on??  Does anybody else make the rear sights for this gun that do not break?

I switched to fixed sights after multiple breakages of the TS adustable sights (which are different). Going into major matches it is a really good idea imho.

Well, looks like I may have to do just that. Which fixed sights do you use? CZ Custom makes some as well

do u use buffer or not?

i know that lpa advertise that their rear sights hold 50k  .i don't know if it hold in .40.

That’s what I went with. I like them. Very robust.

I did. More like 5-10k in .40 imho. The roll pin splits, the blade cracks and the screw under the blade shears. Apart from that, they are great

very sad that such good gun breaks rear sights every 8-10k even with buffers.

can u post pic. of your broken sight.

I don't use the buffer. Which front sight do you use with the cz custom rear?

This is exactly how it breaks 

[yigal]

try to shoot this gun with buffer.  

i use on mines buffers in  9mm with factory ammo.

we have in club 2 tso with over 35k each with no problems, but in 9mm.

I can’t remember. I did need to replace it. I remember using a sight height calculator after shooting the gun with the new fixed rear. 

 

The buffer doesn’t make a noticeable difference in felt recoil or the way the sight tracks btw.

buffer eliminate  hard  impact between slide and frame.

Use a heavier recoil spring and the buffer and I bet you stop breaking rear sights.

So what's your recommendation on the recoil spring then? I use 12#

I don't use the buffer because I'd have to replace it after each practice.  Unlike in 9mm guns the buffer doesn't last at all with 40sw 

[yigal]

i use in 9mm  tso  14lb recoil spring with buffer. pf 142

unfortunately .40 is  a  different animal. 

but as i know  every problem  in handgun can be solved.

I want a polymer lined big magwell for my TSO and Czechmate. Please solve this problem for me (for $100)....

i  already have ergonomic wooden grips for this with polymer magwell on my tso

and it cost much more than 100$

You could do this:

 

Or just get the fixed rear sight used on the TS, from CZ-USA.  that's how I have my TSO setup.  As an added bonus you can use it as a slide racker in a pinch

did you have to replace the front sight on your TSO to go along with the fixed rear sight from CZ USA?

Yep, you'll want to go taller if memory serves me correct.  Since CZ-USA doesn't sell a factory TSO with fixed rear and fiber front, I had to get mine from Dawsons.  They don't have a direct match, but you can get close.

• Factory TS .40 front sight: 7.4mm (.291")
• Dawson .195 T sight: 7.2mm (.284")
• Dawson .215 T sight: 7.8mm (.308")

In my previous 40 ipsc standard, shooting major, I didn't destroy a buffer. I used the same one for over 15k rounds. If you're destroying buffers the buffer isn't the issue, it's your recoil spring.

do you remember what recoil spring did you use in that pistol?

Thanks

Yep, that's my 'custom' work there.  I didn't break it again Yigal, I replaced it with the fixed TS rear sight.
