It's apples to oranges. The Shield is a larger pistol, appropriately carried in an IWB or OWB holster. The Sig P365 is a true pocket pistol with higher capacity. As an owner of the Sig P320 Compact with upgraded trigger and probably around 1,000 rounds through it now, I'm not afraid of Sig polymer pistols. Too many comments about Sig P320's are from those with no experience and just piling on IMHO. Many new designs have had growing pains.
