I had a similar problem and I thought it might be ammo or recoil spring but it turned out to be my fault as I hadn't cleaned the chamber well enough and there was a slight 'build-up". I was using WWB at the time and found it pretty dirty to shoot. Now I use Blazer 'brass case' at the range without a problem. But I also sometimes use HydraShoks, Ranger SXT, and some various reloads....all the ammo is either 230gr. or 200gr. No problems with any of it since I became a little more careful with my cleaning procedures. Your problem cause may be different but improper cleaning was the cause of my problem.rob883 said:older P14 running Blazer ammo will not cycle like it should it does not engage fully so you pull it back a little and release it any ideas ? i am trying new ammo this weekend
