I'll say this, once Mike really got interested in a firearms or group of firearms he really got into researching them.  I remember back in the Compuserve days before he know much about handguns--him being a retired British squaddy and familiar with rifles and other infantry weapons mostly, he started hanging around with us in the handgun section and got interested in 1911 .45s.  He had some familiarity with revolvers--like the one that started this thread, but decided he wanted "a .45."  So he went out and bought--a Smith & Wesson Model 645.  And presented it to us as his new 1911.  

Mike was already a well-liked character and we didn't want to boot him in the arse, but we did gently explain the difference in operating systems.  I'm pretty sure this was before S&W* made real 1911s--um, S&W did dabble in real 1911s, right?  Maybe still do? Anyway...Mike was a little embarrassed, and in later years brought that story up to "tell on himself" more than once....

For you 1911 guys not familiar with them, Smith & Wesson is a revolver maker located in Springfield, Massachusetts.  They've been making revolvers for Americans, the British, and the rest of the world for quite a number of years, actually dating back to the 19th Century.  In the later 20th Century they did quite a nice job dabbling in the double action semi-auto pistol category as well, for a couple decades leading the way in supplying police with that genre of sidearm.  As I said above, I am not confident in saying for sure that S&W also made 1911s at some point.  I suppose if you really want to know you could find a book or check the Internet, but really, who cares if a revolver maker offered 1911s for a year or two.
