hang in there
pull slide back and engage thumb safety into the second notch that looks exactly like the first one. the slide will be locked....then pull out the slide stop, you may have to move it up a little to clear hole. then holding the slide push thumb safety back down. pull slide off the frame. the rest is like any other semi the guide rod is a little different, it mates to the barrel in a weird way...make a note of it for reassembly.
for what its worth mine has been flawless and accurate. hang in there shoot it. with the mag disconnect removed the trigger will improve. some say feg's rival brownings out of the box triggers. browning hi powers aren't known for their out of the box triggers by the way. i have shot both and agree with that. clean well shoot the heck out of it. mine impressed me and for a couple hundred beans i can't complain at all.
