Revolvers may be easier for some people to conceal because of their rounder contours, especially in the round-butt versions. Spare ammunition in magazines, particularly single-column magazines, usually conceals more easily than spare ammunition in revolver speedloaders. According to Evan Marshall , compiler of the world's biggest collection of statistics on handgun ammunition effectiveness, the three most important components of stopping power are shot placement, shot placement and shot placement. With that proviso, I would recommend that you consider the most powerful caliber with which you can reliably place your shots in a reasonable time frame from the handgun that is ergonomic and of practical size for you.

Material is posted on this page for information and discussion only and purports to be no more than the personal opinion of Stephen P. Wenger. UPS has announced that they will no longer accept handguns for ground shipment. Their requirement that handguns shipped via UPS go by Next Day Air roughly quadruples the shipping cost, amounting to an additional, punitive tax. If they won't accept our handguns for shipment at a reasonable rate, ask the businesses from whom you purchase any items to use other carriers.
