the problem im having with my glock 30sf or what seems to me as a problem is when im taking the slide off the frame it struggles a little bit and also when i put it back on. i noticed that everytime i go to put the slide back on, the gudie rod isnt seated. everytime i take it apart i have to seat the guide rod to put it back together. also the back slide rails are lower than the front and it is hard to relaease the slide stop lever when the mag is inserted. any help? it just seems wrong because i never had any of these issues with my glock 27.
