I have a Springfield GI,about 3 year's old.After about 2 magazine's,she does't want to go all the way into battery,I use my thumb to push the slide forward.This happen's with reload's,cast or jacket,or factory round's.This happen's with GI issue mags,Wilson mags,with different spring's,different guide rod's.I have made all sort's of change's to this gun without good result's.The ramp and chamber have been polished,I have tried seating the bullet differently.Tried different load's,I'm lost for a fix. If anyone has any idea's,please help.
