While I've had several Kel Tecs (PF9, P11) before, I have a question about this P3AT before taking it to the range. The slide is very difficult to retract. I've taken the pistol down and cleaned and lubed it. I've also polished the feed ramp and the barrel a bit. But, I can barely rack the slide without it slipping out of my fingers. The only way I can retract it regularly is to grab the slide with all my fingers, pull the gun to me, and rack it that way. I can't hold it with just two fingers. Is this normal for a new gun before being broken in? I've looked at some of the U Tube videos and the slide looks pretty easy to rack????
