This is my Official Field Test Shooting Review for the ASG Bersa Thunder 9 Pro CO2 BB Pistol, make sure to also check out my Table Top Review for this Air Pistol for more information on features, specifications and some nice high quality photos.
In this Field Test Shooting Reviews I test out the ASG Bersa Thunder 9 Pro and put five rounds through my Chronograph to get a real world average fps using a brand new CO2. ASG claims around 400 fps and I got pretty close even thought the fall weather here in BC is getting kind of cooler so there may be room for a bit higher fps during warmer summer time weather situations.
I shoot the ASG Bersa Thunder 9 Pro 4.5mm Pistol from the 20 foot range since I hadn't done a pre test to date. While shooting from a semi rested position at 20 feet back, I was able to get a 2 inch 11 shot group and if I eliminated the two fliers it would have been closer to a 1 inch group. The Thunder 9 Pro BB Pistol shot pretty well centered on target getting 9 out of the 11 shots right in the black center ring. The trigger pull is very typical for this style of double action only trigger, kind of long with a slight sticky click in the middle while the BB chambers and then some more trigger pull with a fairly predictable release right near the back.
You can expect to get right around 6-7 consistent magazines worth of shots before having to change the CO2, that's well over 100+ shots! And even on the last magazine the fps seemed to stay pretty consistent.
Overall the ASG Bersa Thunder 9 Pro is well priced yet offers a realistic looking alternative to the real steel Bersa Thunder 9 Pro and still delivers decent power, more than adequate accuracy and lots of shots out of a single CO2.
