Glad to be helpful. The request was to see if a G19 with a TLR would fit into the Kelty. I immediately thought that it obviously would, but, to be sure, I tested it with a G19X with an ACRO P-1 and a Surefire X200b. (I do not own a G19.)
This Kelty sling bag looks so very “innocent,” yet can accommodate a large-frame sixgun, with up to a 5.5” barrel, my Ruger Super GP100; perhaps a 6” or longer sixgun. I will try to remember to pull my 6” GP100 from the safe, and try it.
