I know this is a long post, but please read and help! My 17L was shooting fine today, until it suddenly stopped firing. The trigger was reset, but no matter how hard I pulled the trigger it wouldn't release the striker. I finally figured out that if I hit the back of the gun while pulling the trigger it would release. At first I thought that maybe it wasn't going fully into battery, but that turned out to not be the problem. I then took out my G17 and swapped slides, so that the reciever from the 17L was now on the 17 slide, and the reciever from the 17 was on the 17L slide. HERE'S THE WEIRD PART.... Both worked perfectly once I switched them out. Once I switched them back to original configuration the problem returned. Any one have a clue what's up? I guess I could just replace all the internals in the 17L, but I'd like to know what's wrong for future reference. Thanks.
