Purchased a Well G291 CO2 bb pistol from BBguns4less. I would not consider this to be a safe or reliable gun. I have received no response from bbguns4less and would have expected some communication this is the second gun I have had from these people, the previous had issues after a few weeks, this gun totally malfunctioned and the experience convinces me that although the prices are cheap this gun was only £29.95 my advice is to pay the extra and go to your local gun shop in person and listen to people who know about guns and buy something with reliability and safety from suppliers who test and know the standard of what they are selling. I wasted two CO2 cartridges which the gun just expelled the CO2 each time through the barrel. Got the third one fixed in, the installing of the cartridge is very iffy. Shot one bb pellet then the gun malfunctioned, when I tried to discharge it again shot all the CO2 out of the barrel. The whole discharge system seems to have failed. It discharges CO2 through the muzzle at an alarming rate with a great volume. Avoid these people and this gun.
