have had this gun for over 5 years and never have had a problem with it. just went out and fired 100 rolunds of pratice ammo and cleaned it after i got home like always. after cleaning i loaded the mags, put it in the gun and tried to chamber 1 round. it jams, the round looks like it didnt get in the barrel. hung up before even getting a little bit in the barrel. so pulled back on it got the round out and tried again, same thing, after a few rounds 1 did go into the barrel but the slide kind of hesitated before the round went into the barrel. took it apart and then back together and am still having the same problems. if it doesn't jam the slide hesitates before the round goes into the barrel.. any help would be deprecated,, thank you
