To set the record straight, the Teams did in fact use the 686. I was both a west and east coast Team guy from 1989 to 2015. The 686 was used when diving due to it's stainless steel construction. We also had Sig 226's which we used when we expected more intense gunfights. I also carried the 686 in a shoulder rig when in the jungle for the same reason. Unless you were constantly cleaning it, the Sig would rapidly develop surface rust on the slide. The 686 would go a week in the bush and simply need a quick wipe down to be GTG.

As for ammo, the supply system had .38 Special, but the local gun store always had .357. Worth the cost out of pocket to get the most out of the 18 rounds I carried.

As for semi-auto vs. revolver firepower, my use of the 686 was a first line backup when the SHTF and my M4/203 was out of commission. Intent was to shoot the bad guy then pick up his AK.
