Tempest in a teapot, folks.
S&W is selling more J-frames than ever before, even though their standard revolvers are produced with the ILS. I don't expect them to discontinue producing ILS-equipped revolvers any time soon.
FWIW, I finally bought one of them, a M&P 340 Centennial, and I haven't had any problems with the ILS.
That said, I do find the new M40 models interesting, and am seriously considering adding one to my 'working collection' of off-duty weapons. The fact that it
doesn't have the ILS won't stop me from buying one.
I've also found myself keeping an eye out for any decent quality older used J-frames, and other S&W revolvers, as well.
