Best bet is if your not confident with it is to sell it or use another firearm. At least with it you have one shot not like the Ruger's with mag safety where you would have none. I luckily haven't had any problems with the early BG380 with laser.
Or you could replace the Mag Release for Bodyguard 380 Pistols with a Galloway precision for $15.00 +shipping
Or ship it back to S&W for them to repair.
