I have a ARMS #40 with tritium inserts/front post inserts. So far, like the sight fine, but have heard that it may not be as bombproof as I would like. Hypothetically, do any other BUIS manufacturers offer the option of tritium (or I suppose, the use of the A2 aperture unit)? I like what I hear about the Troy Ind. and LaRue BUIS, but need the option of trits if I am going to make the switch. Don't get me wrong, I have found nothing wrong with the #40 after several thousand rounds, but like to consider my options. Thanks.
