I have carried mine in both a kydex pocket holster and the SIG branded waistband holster. For pocket carry I primarily only wear baggy pants or cargo shorts and it was very comfortable so long as you have a proper belt to support the extra weight. Most of the time I carry it in the waistband due to the fit of most of my pants but the gun is small enough that either is comfortable. I use the 12 round magazine which is slightly longer so the flush fit or finger extension 10rd magazines should make it even smaller and more concealable.

yes you can pocket carry but a word of caution use a pocket carry holster that fully covers the trigger

Jay, yes Sir it is. I highly recommend this "Pocket Holster" - amazon.com/Custom-SUBCOMPACT-Premium-Leather-Holster/dp/B07CSDB1N6/ref=sr_1_9?hvadid=267898415160&hvdev=c&hvlocphy=9009740&hvnetw=g&hvpos=1t1&hvqmt=e&hvrand=6062057321312173209&hvtargid=kwd-420339472523&ie=UTF8&keywords=sig+p365+pocket+holster&qid=1549579058&sr=8-9&tag=googhydr-20

Jay - It is small enough to be pocket carried, if you are personally comfortable doing that. I would recommend you get a pocket holster to use when pocket carrying. Keeps debris out of the gun, and just adds another level of safety.
