Welcome...from a retired E-9...Army also. I too am a little over 5'8 and 182 so about even. Another factor is where do you live. I live n Mass so when it get cold like this, I can conceal damn near anything short of a SW 500. If I am somewhere warm, this is more difficult
I sometimes carry a g19 or a G30SF. The 30 is nice as it is compact but still has the punch of a .45. The good news is you can probably use the same holster
The downside is the round count. The 30 is only 10 rds.
