Trigger Pull: The trigger pull on the ASG Bersa Thunder 9 Pro has a medium and double action only fairly long pull with no real sticky areas in it. The release is right at the back of the mag well and just before the release there is a slight click where I believe the BB is loaded into the open break, just before it closes on the return of the forward moving internal barrel.
Accuracy: This part of the review is yet to be determined (Click here to watch the Field Test Review for this ASG BB Pistol), I would expect to get reasonable results in terms of accuracy, power and CO2 usage since the design of this BB pistol is very CO2 efficient. The sights do have white dots front and back which will make target acquisition good but they are non-adjustable so hopefully it shoots well centered. We will have to see how well the ASG Bersa Thunder 9 Pro does during the field test shooting video review...
Build Quality: So far I have not been disappointed with any of the ASG airguns; even the low cost versions seem to be with durability in mind. The ASG Bersa Thunder 9 Pro is a pretty basic low-cost mostly plastic BB pistol so you do get what you pay for. There is a fair bit of metal internally which gives the Bersa Thunder 9 Pro some weight - more than you would expect from an all plastic outer shell. The BB stick magazine is also all metal adding some additional weight. Fit and finish all seems good, no complaints and the simple build design with few moving parts means there is not a lot that can go wrong or get easily broken.
Realism: The ASG Bersa Thunder 9 Pro is very accurate replica of the real steel version in terms of looks, with full licensed Bersa trademarks and even the 9x19 caliber markings in the slide ejection port area. The only real obvious indication that it is not the real version is the fact that it is plastic and the screw holes on the right side of the gun where the two plastic halves have been married together. At least the slide does not have any screw holes in it.
Comments: As you know, my preference is more towards the all metal guns with lots of working parts, full size drip out magazines and blowback action. The problem with these types of realistic airguns is that they can be expensive and sometimes a bit temperamental with all the working parts designed more for realism and less for simplicity. Generally speaking, the more realistic the gun the more of a sacrifice is made to give up things like power, CO2 efficiency and even accuracy. The ASG Bersa Thunder 9 Pro is made to look like the real steal version but it does not try to replicate it mechanically and so as a functional BB pistol it will work very well, yet give you the look and feel a real 9mm Bersa Thunder 9 Pro.
