Hi new memeber here I am a proud new owner of a cz p10c as of December 30 of last year ... the gun shoots great easy to clean and love the trigger but I have one issue and I hope y’all can help . I took it out of box and apart wipped excess oil off and lubed the pistol afterwards I noticed that the slide lock works perfect when a magazine is in the pistol . When a magazine is out however the slide lock works on the right side always but on the left side of pistol it only works some times ... in fact if I take pressure off it immediately goes forward I’m at a loss please help thanks
