Derya pump and bolt action 9mm pcc

Held a 16" synthetic stock version at SFRC - really wasn't all that impressed for the price.

It didn't feel as toy-like as a GSG-16, but didn't feel nearly as good as a TM22 Pro, which typically retails for at least $100 cheaper.

As previously mentioned, no slide release button. You basically just force the slide back and forth with brute strength. If it did loosen up with time / use, I'd be slightly concerned about OOB detonation...

How much "brute strength" are we talking about and would adding something like a Magpul RVG forward grip help?

Pump action firearms have existed for over 100 years. Most Remington 870's / Mossberg 500's can cycle as smooth as butter. It's not exactly rocket science to make a pump gun work smooth and easy.

I'm not certain to understand why this gun would be different or how that supposed "spring assist" works? Also, there's literally ZERO information or videos on these on the interzones.

Do you really need to use the same brute forth in both directions?

The bolt action is starting to look like a better option.

Is it a locked breech design or is it unlocked and relying on the spring and whatever resistance in the system to keep the breech closed? There is no reason for needing brute force in a locked breech design.

Depends on the action. I agree very little force is required with a locking breech, but if it's essentially a blowback action relying on spring force and mass to keep it in battery then you might need a lot of force to operate it. Sounds awful at this point.

I agree. Now I'm having regrets of perhaps "pulling the trigger" on one of them too soon, lol! It's usually a bad idea to be one of the first adopters of a new product or model, because you become the manufacturer's guinea pig.

That being said, I can see how a simple blowback with a spring assist could be cycled very fast while shooting. The fired round would recoil the bolt and provide the initial inertia to cycle it fully by hand, if your timing is right. Paul Harrell called it "pull-rack".

Also if this setup is indeed the way this firearm works, then in theory a lighter action spring and a forend disconnect would make it go SA with proper ammo....

"Brute strength" may have been an exaggeration on my part - it's not so much that it's hard to cycle, it's that it's not smooth like any shotgun I've ever picked up (certainly no spring assist either), and the effort required to cycle it in either direction is higher than I would have expected.

Yes, it felt as if I was applying the same (or at least very close to the same) amount of force in either direction to cycle the firearm.

Ar this point, I'm also hoping to get my hands on a bolt version to see how it compares.

Wish I could provide a more definitive answer to your question, but I'll have to abstain, as I don't want to give the wrong answer and muddy the waters any further than I already have.

All I can say is that the cycling action was very short / abrupt, it felt like an equal amount of force applied in either direction, it wasn't very smooth, and it didn't feel like there was anything holding / locking the bolt in place.

Can't remember if I mentioned it or not in my original post, but the mag release is a long lever/button design. It's located right where I like to keep my finger resting against the receiver of a firearm when I'm trying to practice good trigger discipline. At one point, when I was inserting an empty magazine, I was resting my finger on said lever/button hard enough to actuate it, which allowed the magazine to be over-inserted, preventing me from fully cycling the pump action. Perhaps this is something witnessed on other PCC's, but I've never held a PCC where I rested my finger on the mag release firmly enough to discover that I could over-insert the magazine in the first place.

Again, my overall impression was that I was not impressed given the price being asked for this firearm. Perhaps if one owned one of these and took the time to learn/adapt to all its little quirks, it might be a reliable little pump gun in a calibre that got hit hard by the OIC & handgun bans... but for me, it just didn't feel very intuitive / high-quality / confidence-inspiring when I handled it.

Hopefully someone like BATS on YouTube will get his hands on one and do a more in-depth review.
 
Tenda is now sold out also, fellas and fellettes...

There were 5 in stock about 12 hours ago. They seem to sell out fast everywhere.

Hopefully that means more stock coming in and more similar SBR designs for the future!

:)

Sounds like there is some sort of mechanical lockup and not just a spring.
The reviews and feedback will no doubt be coming in fast!

Thanks for sharing your insight.
