I have a Beeman under lever and think it’s a good bag for the buck. I purchased the 1357 in .177 and wish I had purchased the 1358 in .22. The trigger isn’t great but I oiled it up and the gun is very shootable without any modifications. I shoot almost entirely off hand and for me the under lever cocking is the best cocking system I’ve tried on any bullpup. I dislike the fiddley cocking levers, on most bullpups, that are back next to your ear. My main gripe about the underlever Beeman is the availability of additional magazines. The Beeman 10-shot auto-indexing magazine in .177 Cal., for the QB II model 1085 CO2 rifle, Chief II PCP rifle, and Commander PCP rifle will work in the Beeman 1357. I assume that the Beeman 10-shot auto-indexing magazine in .22 Cal., for the same Beeman rifles, would work in the 1358.
The magazines for the Benjamin Marauder and the Umarex Gauntlet air rifles will also fit the Beeman 1357; but DO NOT TRY TO USE THEM! Because of the oblong hole in these magazines, the pellet push pin will pull pellets out the back of the magazine when the bolt is retracted. The pellets that come out the back of the magazine will fall down into the receiver and stop the gun from firing. The pellets end up blocking the hammer from striking the valve. If this happens, the gun will have to be dissembled to remove the pellets. I did it twice; before figuring out what was happening.
