I been looking at a couple of the small .380 EDC type autos and thinking about adding one to the kit. In doing this it would be another option then the current small frame .38spl revolver I carry. so to compare available ballistics: .380 ACP Self defense type load Hornady Critical Defense Ammunition 380 ACP 90 Grain Flex Tip 1000fps with 200ftlbs at the muzzle Speer Gold Dot Ammunition 380 ACP 90 Gr. J H P 900fps with 196ftlbs at the muzzle Winchester Super-X Ammunition 380 ACP 85 Gr. Silvertip HP 1000fps with 189ftlbs at the muzzle All of which would be something to hold on to in a pistol the size of a Ruger LCP or Kel Tec P3AT .38spl. +P Self defense load Hornady Critical Defense Ammo 38 Special +P 110 Gr. Flex Tip 1090fps with 290ftlbs at the muzzle Hornady Critical Defense Ammo 38 Special 110 Gr. Flex Tip 1010fps with 249ftlbs at the muzzle Speer Gold Dot Short Barrel Ammo 38 Special +P 135 Gr. JHP 860fps with 222ftlbs at the muzzle Winchester Super-X Ammo 38 Special +P 158 Gr. Lead HP SW 890fps with 278ftlbs at the muzzle I've shot +P ammo in my small .38 no problems holding on to it or getting back on target quickly though the muzzle flash can be amazing. The small autos hold 6+1 and are quick to reload with real long hard to control trigger pulls Striker only. Alloy or Polymer frames. The small revolver holds 5 rds is slower to reload with speed loaders has a short crisp DA and a tight lt wt SA trigger exposed hammer so even the first round can be SA. Stainless steel throughout. The autos weigh less and are thinner but both styles conceal about as well as the other. In speed they appear to be a match (of course with many different loads available they can be matched up just about any way I tried to show very similar loads) in energy the .38spl has a marked advantage with about as much as a 31% advantage in the Hornady +P load and even in the std .38 spl load theres a 18.5% advantage. So it would seam to me the ballistic stopping power advantage would have to go to the .38spl The advantage for the small auto is the capacity and reload time. MUCH bigger chunk of copper and lead can come flying out of the .38spl up to a 75% bigger slug with the common 158gr offerings. The functional advantage would have to go to the small revolver with almost no chance of a jam, the advantage of the shorter trigger pull and the advantage of the target like trigger in SA. off set by the more fiddly loading characteristics. And here's one you might not think of a small revolver does not spray brass all over the area. So lots to think about as I shop for a small auto.
