Over on Glock Talk there is an interesting discussion regarding the preferred action type for defensive pistols today. A poster there made a comment that Glock type double action pistols and there brothers in arms manufactured by other companies (i.e., Springfield XD, Smith and Wesson M&P, etc.) were becoming more popular than sa (various 1911's) and da/sa (Sig Sauer, H&K, Beretta, etc.) type pistols. Of course, being that it is posted on the Glock Talk blog page you would expect folks to mostly come down on the side of pistols with actions similar to Glocks. I thought I'd post the same question/comment here to see if there may be a more balanced response from folks that frequent this site. For the record, I own Glocks, Sigs, CZ's, Smiths and Wesson, and Colt pistols and my edc is a Sig Sauer P220 Carry (da/sa), but also carry a Glock 30sf from time to time. What action type do you prefer?
