hey guys. im a fairly new firearms owner and therefore woefully underskilled in the more technical aspects of firearm maintenance. however i recently inherited my grandfathers old pt25. its an awsome little thing and i highly enjoyed shooting it. however my last time out at the range i drop it and now the tip-up barrel wont stay down/closed. i was having some trouble with it before hand, (sometimes i had to press really hard to get the barrel to stay down) but after dropping it it wont stay closed/down period. "THE BARREL" can be placed in its original position (and the gun can still fire) when held down firmly, but swings back up and open when i let it go. obviously this causes concearn for safety and shooting effiencey. like i said before i enjoy this little gun and its the only one i own, any suggestions on how i can fix this annoying little problem would be highly welcomed. thanks for your time and help.
