I had the same problem on a rifle I built, the cure was a heaver buffer as it was over gassed. I bought a KAK buffer that comes with 9 weights so you can fine tune the buffer. It took a 5.4 ounce buffer, oh it also reduced felt recoil.
Are you still working on a military base, if so it should be posted at the gates to the base. Most bases do not allow concealed carry ecept in very special cases. Note if it is against base regulations if caught you are committing a felony.
I have this one and really like it. http://shop.hiddenhybridholsters.com/HHH-C1-HHH-C1.htm?productId=4 I also have a Serpa CQC for a model 30, works fine.
roger what they said, you'll probably get a call around February, they had the last induction a month or two ago so I imagine they'll wait to see how many folks fail to renew 1 Jan then induct to fill the gap...
