So just a FYI for anybody else really running these guns even semi-hard use. I’ve cracked one of the 13rd mag base pads from dropping on concrete during reload. Email to S&W with picture and description, responded to next day asking for serial number and address to send replacement part - showed up about a week later, good job S&W.
Within 2 weeks, cracked another one doing reloads in dry fire - dropping onto a plywood floor. It appears there is a seam right in front that is vulnerable. Just slapped duct tape across this one since it stays loaded with dummy rounds mostly and have started out cushion down for dropping mags in dry fire, plan to contact them again eventually too. But I do shoot this gun in IDPA matches somewhat regularly and in practice sessions with reloads - kinda like a carry gun should be. Maybe something could be done to re-Inforce them or something from S&W, or if after market base pads became available, I’d swap them out in a heartbeat for aluminum base pads.
