I recently purchased a new P-3AT and spent a littlw time on the range last weekend. I did have 3 jams with it, but after doing a lot of reading on here I'm not too worried about it (yet). I have noticed that many people refer to "greasing" the slide rails to improve performance, but I haven't seen any recommendations on what grease you should use......any suggestions/recommendations? I may also spend some time on the feed ramp area with some sandpaper before the next trip to the range...... Thanks for the help!
