I'm 6'4" 250 lbs.
I have been carrying my Wilson Combat CQB in either a milt sparks IWB Versa Max 2 with a Beltman belt or a Galco Miami classic shoulder rig, depending on how I'm dressing.
I know there's a lot of hate for shoulder holsters, because of the muzzle sweep (among other things), but with a 1911, you have to train to safety off AFTER you clear your arm.
The shoulder rig is infinitely more comfortable when driving for extended periods but I cannot reholster one handed yet. This could change as it breaks in, because years ago in a different state I carried a S&W 411 in the same type of holster and after it was broken in, the gun was much easier to draw and reholster.
Neither set up has gotten me called out for printing, but then again, I'm a middle aged dude - people aren't checking me out in detail.
Not a glock guy at all, but it seems like they've improved their triggers since Gen 1 (the last time I shot one), so I'm toying with the idea of a G19 and I'll probably get a crossbred supertuck for that and use it with my Beltman belt.
