Most people who own firearms have no clue how to handle them safely or hit a paper plate size target at 10 feet. And you want them armed inside a confined space?
In preparation for RH shoulder surgery *3 weeks ago) I practiced more LH with 43 and got a LH IWB. While not as good as 2H RH I get body hits at 7m. Not planning on getting into a shootout but at least can get out of a shoot out.
Also have a tactical knife in left pants pocket and in my sling.
And yes I live sw of Denver. Cannot remember last time I went to Boulder.
