Just picked up my shield .40 toady! only had enough time to put 100 rounds through it unfortunately.. And it will do the whole of out of battery thing.. But even with the holster that i have for it which is very tight (the holster needs some breaking in) it does not cause the weapon to come out of battery i really dont think this whole "issue" is anything to worry about unless S&W actually says something.. Im very happy with this little weapon cant wait to get it in 9mm.
