I recently bought a brand new glock g19 gen 4. (around march 2012).. only shot 85 rounds through it.. took it home and cleaned it and put it back togeather.. The other day i was gonna oil it a little and go to the range, but couldnt get the slide off. was just wondering if their was anyone on the northwest side of indy that could lend me a hand and help? thank you for taking time to read this.. PS: i can dry fire the gun but the slide just wont come off..
