Hi, just bought a Hi Point c9 last month and have to say it is a very accurate pistol! I grouped them better with my c9 than with my ruger p89. Had a question about the slide failing to return to full battery on occasion. Sometimes the slide fails to return to full battery leaving a 3/16 gap between slide and breech. I bump the back of the slide and it will return to battery. My question is is there a fix to this problem? New to the forum and would appreciate any help.
