I recently purchased a shield plus, put 100 rounds through and as normal routine, wanted to clean it ASAP. i could not get the slide to remove. tried the sear pin per instructions, tried pulling the trigger still nothing. i decided to return to S&W. went to my FFL ,they as well could not get slide to remove. First of all, has anyone had this problem? could it be a recoil spring that was improperly installed at the factory? Or is it just the worthless sear pin? Now that S&W has had gun for 2 weeks I checked progress. The representative informed me that it would be at least 6 weeks until I seem my gun again and someone should have told me that. Said summer vacations slow down the repair process. Well if summer vacations slow down the repair process then how would S&W feel if no one purchased guns during the summer knowing that their quality control is failing.
