purchased the shield 40 in july 2012. Had the issue with the mag dropping out from day one. Called smith&wesson and sent the firearm back at there expense. received the firearm back within 2 weeks with new mags and no more problems . Haven't had a problem sinceI'm considering purchasing the M&P 40 Shield. Anyone encountered the mag ejection problem with them? Do you know if it's been fixed. Any other info would be helpful and appreciated. Thanks!
