You'll need to call unless someone else knows for sure. SRJ does not give a discount but participates in the discount program that S&W, Glock have. If active military are covered then I'm sure that SRJ would comply. Give them a call tomorrow.
I'd call before going. I was just there today and they were sold out of a lot of guns, especially the ones without night sights for $398.20. I dont think they had any of the Glock 17, 19, 22, 23 or 27's.
