Diana 340 N-TEC Premium air rifle

  • German Nitrogen-Piston Technology
  • Breakbarrel
  • Single-shot
  • Rifled steel barrel
  • 2-stage adjustable, modified T06 trigger
  • 11mm optics dovetails
  • Fixed metal front globe accepts interchangeable sight inserts (not included)

Here are the benefits of a gas-piston powerplant:

  • Smoother cocking
  • Smoother shooting
  • No spring torque
  • No spring fatigue, even if you leave it cocked for hours
  • Functions perfectly in cold weather
  • Lasts longer than a metal spring

Diana air rifles have an excellent reputation because of their durability and quality. They've kicked it up a notch with the N-TEC gas-piston powerplant! Diana's proprietary German Nitrogen-Piston Technology delivers smooth shooting, dependability and a decreased cocking effort. There's no spring torque because there's no coiled metal mainspring!

The high-quality metal sights are a nice switch from the current trend of scope-only guns. The front globe lets you change inserts (not included). If you want to mount a scope, the 11mm dovetails will accommodate your optic of choice.

Use your Diana 340 N-TEC Premium air rifle to hunt small pests and critters at close distances.

Things I liked: Typical RWS quality save for one issue I will discuss below. I have the Luxus version with a walnut stock. It comes to shoulder well, the swell in front of the trigger is perfect for the artillery hold. Very accurate with the addition of a Williams peep after fashioning a stop to keep it from sliding down the rail

Things I would have changed: Throw away the current RWS rear notch sight. Too much wiggle and plastic. Mine would not allow precise or consistent firing. I put on a 1989 version from my RWS M-36 and the Luxus was transformed into a ragged single hold shooter. The older rear sight was based on a recurved spring that was manipulated by an adjusting screw. On that spring blade, was mounted the rear V notch structure but one with the choice of four (4) different notches. RWS should return to this older and better system.

What others should know: This is a well built RWS springer that double-recoils harder than my 34-P, also in .22. This, like other RWS pieces in my inventory, is a potential heirloom piece.

Things I liked: Typical RWS attention to fit and finish. Very stiff at first but that is loosening up. Shoots very hard and consistently but....

Things I would have changed: ...the current RWS rear sight is poorly done. It wiggles and wobbles and will not stay consistently set. I changed my sight out for one from my '89 Model 36 that uses a spring steel leaf instead of a hinged support for the rear notch. Suddenly, the rifle that was inconsistent began to make one-ragged-hole groups. Go back to the rear notch of earlier years (that also have four choices of notch, BTW).

What others should know: Use the artillery hold, and replace the rear sight. I will be installing a Williams Peep with Target Knobs. In combination with the tunnel front sight, it renders RWS springers tack drivers. Keep the rifle clean and lubricated and it will be a legacy to one's descendants.

Things I liked: Purchased the P340 in Dec. to go with my P34 springer that I purchased way back in the oughts. The T06 trigger in the P340 is whisper light in comparison to to the P34's TO5 trigger. After 500 shots, I've found the P340 to be just as accurate as my older rifle and a shade higher in velocity. Once accustomed to the new trigger, I prefer it over the older T05. The powerplant is smoother, a little harder to cock, and has quite a different feel at launch than the P34. Worksmanship is equal in the 2 rifles, both exhibiting the quality that one has come to expect from Diana. In a nutshell, love my new airgun!

Things I would have changed: Not as fond of the new stock, the ridged texturing on the forestock is a bit rough, preferred the checkering on the P34. The front of the forestock also just out at an angle forward, the P34 is rounded, which I also prefer. Not to big a deal, but need to watch fingers when closing barrel. Also not a fan of globed front sights, too easy to bust, would prefer a simple blade front sight.

What others should know: Both air rifles are outfitted with UTG 4X30 scopes, dime sized groups at 25yrds. The ammo that both seem to like the best are JSB Exact Jumbo(15.89)

  • Christopher from USA asked:

    Is there any way of adjusting the piston internal pressure to vary the FPS to suit different needs (Hunting to Target)? This is one thing I really like about my Weirauch HW90.

    • Rudedawg from USA asked:

      The questions/answers on the 340 N-tec below were all posted over 2 yrs. ago, has anyone purchased this rifle within the past year or so who can offer any updates or improvements on quality?

      • anthony from Canada asked:

        Do I need to use the artillery hold for this airgun

        • Tyler from USA:

          It is recommended for gas rams just like springers. Although I have found that you can get away with a bit more of a tight hold on gas rams as they are simply faster than a spring and a tad more forgiving. Just be consistent with your hold and that should give you good results.
