How do you know if you can use +p rounds in your gun? I can't find anything that says, definitively, that using a +p round is "ok." I have found reviews that say they used +p in the gun. Is a .380 round a .380 round regardless of the grain/+p (I mean, of course, that different ammo has different characteristics, but how do you ascertain interchangeability/compatibility)? This concludes yet another neophyte inquiry. Thank you for your attention.
