Concealment button-up shirt with velcro
Mrshonts and I went to the local gun show today, and since mrshonts will be getting his carry permit soon, he's been hunting for different concealment options.
He found this nice dress shirt with a velcro pocket that's easy to open. There were different color shirts; white, green, denim, etc., and they are of well-made, durable material, and they are made in the U.S.A. The pocket gives you access to a shoulder rig or belly band. Mrshonts opted for the belly band, and his K40 slid into it easily.
I don't have the manufacturer's name, but the seller's website is here. The shirts are not listed on the site, but she has an email address listed.
