Derya pump and bolt action 9mm pcc

[762mm]

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.

Waiting for a 12" bolty 9x19mm to show up, that would be great for popping squirrels amazingly lol

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....
