Title: Samopal USA trigger upgrade
Post by: Aster on July 16, 2021, 06:07:37 PM

Found a gunsmith in the US that does VZ trigger upgrades, turns out its Dan Brown from Czechpoint.
Anyone here have tried getting this upgrade?
The overtravel adjustment screw seems straight forward, curious to know what reduces the pull length safely.

I don’t  know but I can tell you that Dan knows his stuff and will communicate well with you.  He’s doing some pin and weld work for me now.

That looks pretty bleep cool and looks like it eliminates my chief complaint about the VZ58 - the squishy trigger pull.

Kind of pricy, though, at 300 bones.

Anyone who’s had this done, please let us know how you like it!

I'll be taking them up on this in the Spring.

You can do your own over-travel stop.  ForcedMarch used to offer for about 1/2 that (check stickies) but requires folks to send who rifles now after some reliability/safety issues with just trigger pack.  The Zendl disconnector/gremlin buster is also supposed to result in improved trigger pull, but I haven't tried.  The take-up is entirely to do with the disconnector and sear engagement/space between the disconector nub and the sear leg.  Easiest would be to adhere shims to sear until you're happy and then have single shim permanently attached...  Polishing/adjusting sear and striker interface and sear leaf spring is primary determinant of trigger pull. 

Of course all of this is potentially dangerous, so would make any modifications to spare parts or have spares on hand before diving in...

IIRC, the CNCW/Bonesteel steel trigger group also advertises some improvement on take-up and over-travel.

^ Yeah, I don’t think I’d trust myself to do any trigger work - best left to the pros in my case!

Certainly don't blame you.  Knowing your limits is important.

But also important to know how the firing mechanism works, even if you don't personally mess w/ it.

I’m definitely interested if anyone has had this trigger work done. Especially the logistics (I’ve never sent a firearm for work) and the reliability

I am too. I was instructed to wait till 11/10 before he’ll be taking new work. That was only an estimate but I’m gonna try to fill out the paperwork on the 10th

Got my rifle back from Dan. It’s absolutely fantastic!!  I haven’t put it on the scale yet but the trigger is just like his video, crisp, smooth and no extra travel anywhere. Also, dealing with Dan was a pleasure, he under promises and over delivered. All his time estimates were accurate, he walked me through the shipping process and he communicated with me throughout. Best 300$ I’ve spent on a rifle in awhile

I feel a little less ridiculous setting up my rifle as a suppressed scout now that it has a quality trigger.

So he pulled your barrel and threaded on a lathe?

So if you are going to suppress it, you need to consider the concentricity of the bore.  If it is a Lothar Walther and they are all lathe threaded, maybe you are OK.  If not, you really cannot.

Just dropped mine at UPS. Hope to get a quick turn around and get shooting again.

I fire it suppressed just fine. I turned my indexed adapter on the barrel

Really excited for you. If it’s like mine (of course it will be) you’re gonna be very happy to write that check. My dads probably gonna send at least one of his to Dan after shooting mine

Got tracking for it's return trip home. Can't wait! Just have to deal with the fudds at the range griping about "that new fangled semi auto" and "commie guns".

Got the rifle back today and put it back together and want to share my thoughts.

The Samopal service advertises:
1) Reduces long trigger pull (often referred to as a "squishy" trigger pull). 
2) Decreases overtravel.
3) Shortens length of reset.

It seems to have gotten rid of most of the "squishy" trigger. That was definitely a complaint with my original trigger.
I like the overtravel stop. That works well and helps to make the trigger feel more crisp.
I don't remember my reset length being something I noticed, or cared about. Shooting fast, I don't really notice reset.

Like an idiot, I didn't measure the "before" trigger weight. It varies between 5 and 5.5 pounds now on my RCBS trigger gauge. To be fair, there isn't any mention of trigger weight reduction and (THIS IS NOT A KNOCK AGAINST DAN OR HIS WORK!!!!!) I did not proceed with this service expecting that. I would not recommend this trigger work if you are looking for a match trigger, but like I mentioned, there is not promise of this on their webpage. This does not get you into SSA-E territory, but it does create a great fighting rifle trigger. If you currently have a terrible trigger, this would most likely make you very happy. Overall, I'm pretty pleased. For a forever gun, or trying to get the most out of a rifle you plan to compete with or just shoot a lot, it would be a good upgrade.

Once the weather gets nicer, I'll try to get out and run it. If I remember, I'll post my thoughts.

I just checked my pull weight, mines at 4.8# pretty consistently. You’re definitely right, it’s not a crazy match trigger. The difference in reset is exceptional, I didn’t measure but I dry fired 20-30 times before I sent it. Imo, it’s a perfect trigger for the VZ, at least for me. I shoot it a lot, suppresses and noisy, regularly carry it in a vehicle and wouldn’t be against grabbing it in a zombie situation.

Anyone else have this trigger job done recently? Results?

What was your turn around time?

I had Dan perform this surgery on all three of my Vz.58's.  Two different times (one order of two, and a later order for one).

In both cases turnaround time was pretty good for a single-person custom shop.  Few weeks?

It's by far the best trigger upgrade available for the Vz.58.  I'd do it again.

Sounds good!

I’ll be sending mine Dan’s way soon. I’ve got a CNC Warrior trigger group to go with it!
