Open pockets - not good - Tru-Spec 24-7 Short Sleeve Concealed Holster Shirt

So I ordered a white and black one of these, since they looked like a cheaper version of 5.11's t-shirt holster. I own 6 5.11s.
I put on tru-spec's shirt, thinner padding on the holster pockets - AND Wide open!! No snaps, no velcro, I suppose they think friction is good enough - not. I put a S&W 637 .38 snubby in (safe and unloaded). The butt of the gun is about an inch from the holster opening just putting it in. I jumped up and down, shimmied, wiggled, etc. The pistol almost fell out. Without some owner initiated modifications, this shirt is dangerous. Of course, they can't put snaps or velcro to hold the pistol secure, 5.11's lawyers will have a fit. So if you buy these, and they are pretty good, except for that safety issue, make sure you put some on the holster openings to keep your pistol from falling out.
