KWC co2 desert eagle
 

so i got my kwc desert eagles and so far they seem nice but i only get 2 mags out of a co2 cart...is that normal?
some time when i try to put the hammer back slowly and it tries to go into a weak fullauto mode?
and the safety has two settings; a red dot for safety, and two unmarked positions that seem similar but something is different...

Yes that's normal. Some guns only get 1 mag of BB's with 1 charge of gas (propane mags I mean). And blowback CO2 guns usually get 2-3.

hop up
 

i owned a green gas d.eagle ten years ago and had no problem locating the adjustable hop up located under the slide on the back end of the barrel...but now with these co2 ones i cant even see the rotatable hopup...? do i stick a flat head in here?
