Always read the owners manual before operating any gun.
This gun is NOT recommended for the masses for reasons cited but still a fun gun to shoot. I've never had a problem with this gun which was 100% reliable. A better source for information about reliability are the comments below as I review guns and do NOT long-term test them. I really like this gun. It has pushed the Crosman P10 out of the top spot as my favorite airgun to shoot. It's a BB gun and knows it.
The trigger has a little creep and feels spongy for a single action but compared to other CO2 powered BB guns it is above average.
The other gun shown at the end is the Tanfoglio Witness Full Metal Blowback 1911 - an excellent gun
This gun is made in Japan which only makes it more interesting.
There is a Philips Screw on top of the slide right in front of the rear sight. You can see it around the 8 minute mark. It doesn't look very good.
