I've got a HW40 and a little while back I lost all pressure from it, wouldn't even fire pellet out of barrel. Couldn't work out why but realised I had left the pistol in car overnight and got cold, so warmed it up indoors for few hours and worked perfectly fine after that, Just a thought?

To save me doing a lengthy explanation again, I would suggest you put in the search box "Beeman p17 seals" Loads of threads on this well known seal and deburring air hole problem with p17's. ATB. Pete.
