With a full sized gun, in my case a SIG P-226, the butt prints rather badly in this jacket. That may be partially my build or the fact that the jacket is not a "loose fit" on me.
I find that getting to the Velcro seam and then to my gun is much slower than my usual IWB carry.
Lastly, the elastic has been reported to stretch out in time or rip completely loose.
For the price of the jacket, I was disappointed in it for a CCW purpose. On the other hand though, itís nice and warm!
