Looks like my new S40 is hit with the trigger reset bug. Have checked out Big Taco's trigger reset tutorial. However, before I continue, let me run my scenario out to the club. Picked it up Friday as it came in that day. So once I got to the FFL/range, I took it like a little kid at Christmas and went into their indoor range. Yeah, I know, I probably should have taken it home first and cleaned it. But didn't. Had my Glock 27 with me so I was ready to go with some .40 ammo anyways. I get down into the range, and started off with some 180gr Speer Lawman FMJ. Seemed like every other shot was a stuck trigger with no reset. I coulnd't figure out what was going on as I didn't know about the trigger reset plague. I'd drop the magazine, clear the chamber and reload, and same thing. Over and Over. Then it dawned on me the trigger wasn't resetting after 3 magazines. After the shot, I would nudge the trigger forward with my trigger finger and then proceed to the next round. As my session went on, it seemed the issue began to resolve itself. I probably ran about 250+ rounds through it that day and can say it did get better as it was not occurring with the initial frequency. Although, it still did occur enough that I decided that, for now, this will not be my EDC. Since then, I have taken it home, cleaned up the carbon/powder residue from the slide, frame, spring, etc. Given that it did seem to begin to correct itself, would you all recommend another 200+ rounds until a diagnosis of a fix must be made? Thanks ladies and gents!!!
