I carry at the 5 o’clock, IWB Milt Sparks custom holster.
Light jacket, slightly oversized.
Driving is more comfortable than you would guess, but given poor access while seated, I will tuck it in front, leaving holster in back.
Sig P220 is larger than most carry weapons, so I carry at 5 o’’clock to avoid “printing” and maintain easy access.
P-220 is an excellent on / off duty CHL rig.... 45 or 38 super.
I carried same when I was a deputy.
As to this subject I have a rule. No checkered or rubber grips. The clothing tends to creep an cling on such. CHL grips should be smooth.
Also iwb style holsters tend to not print at all if worn properly.
Stay Safe ....
HK P2000 (.40) or HK 45C both in Milt Sparks VM II’s (worth the wait) at 5 o’clock. Loose cargo shorts and wild print shirts untucked in summer. No problems!
