...As a partial answer to a couple of points raised earlier; The New York Police Department figure are still the most often quoted, and most realistic as far as Police type shootings go. Virtual contact distance, 2.5 yards or less , 2.5 shots , and 2.5 seconds. There's a very high percentage of shots missed, even with very highly trained shooters as well. Assuming the figures are still correct, there's really no advantage to be gained by having larger capacity weapons, apart from the perceived, shooters increased confidence in his or her weapon. From a personal level, if anything increases user confidence, I'm basically all for it, be it an issued rabbits foot or a high capacity pistol ! It should also be noted, than when NY PD switched to semi-autos, they allowed the "older officers" to retain their revolvers. In the latter stages of the 38 Specials operational life, the so called , "FBI load" ... 158 grain, semi wad-cutter, H/P was a VERY effective round ! The 38 Special got the bad rap, largely from the period when the 158 grain round nose was the standard issue load, that same time frame also saw the spare rounds carried in loops (RCMP anyway) in the handcuff pouch, or a modified even older issue, pouch/box carried just in front of the holster. With the advent of speed loaders, things changed dramatically, again, personally, I can see little real world advantage of pistol over the revolver, as the revolver is quicker to train raw recruits to a reasonable level of competence, and it's a little more forgiving in the sense that one only has to grab and squeeze, bear in mind that relatively few Police Officers are willing , able or interested, in honing their hand gun skills beyond annual qualification levels. Basically, given appropriate loads, there's little to choose between a high performance 9mm and a high performance 38 Special. As to the Sig's being RCMP issue; yes they were, to ERT/SERT and some Dog Masters . There were some (limited) failures due to cracked frames, but this was after, probably, 50,000 rounds or more, of full service loads, and even at that, the failure rate was low ! The SIG was rejected based on single/Double action trigger, non stainless steel, and most importantly, the cost over all to make the transition. Would a S&W 686 with round butt, and fixed, "glow in the dark" sights been a better overall choice ? Given that personal preferences and uses, allowed a choice between the 357 Magnum or the lighter recoiling 38 Special, maybe ... David K.
