No more DA/SA for me...Glock had it right, but S&W did it better!
I started with handguns when I was in my teens, and over the years have bought/shot/or carried almost every type/size/ or caliber. When I first got my Concealed Carry permit, I went with a 3" 357 revolver. I shot it well, and it was pretty easy to carry. On some occasions I "down-sized" to a .38 special in a 2" snub...but that was before the semi-auto craze took the industry by storm. I fought the transition for a while, since I shot the revolver very well, and was comfortable with the platform.
Then I went Glock. The G19 first, and what an increase in firepower! 15 rounds at the ready! Sure, it was bigger. blockier, and heavier, but did I mention it had 15 rounds at the ready? Move forward, trade for a G26, a few less rounds, but easier to conceal, and shot exactly the same as the 19. Same trigger pull with every shot, and I knew every round would go where it was supposed to go.
The "Slimmer" than a Glock fad then hit, and everyone was going for mini-guns. The .380s, single stack mini-9's, .32s, you name it. As long as it fit flat in your pocket, there was a buyer for it. I tried a few, and found the SA/DA gave me more trouble at the range keeping round #2 where it was supposed to go. That SA/DA transition for the 2nd shot, and subsequent follow-up shots were nothing like a revolver trigger, and I never cocked the hammer for any of my revolver shots, and I realized I didn't have to compromise!
Pictured below is what many consider to be the finest single stack "mini-9" ever made: based on the Smith & Wesson 3913 frame, it is the 3953: A DAO pistol. Every bit as slim as the 3913, even more-so if you count the missing safety levers, and with 8+1 capacity, giving me 30% more shots than my S&W 13 revolver. Same trigger pull on every shot. Easy to conceal. Light weight with an alloy frame. And chambered in the respectable 9mm, which is arguably one of if not the most popular handgun cartridge in the world.
I also recenly purchased the same gun in .40 S&W, only slightly longer in the slide and uses the same holsters, the S&W 4053. It's my first .40 S&W handgun, and I think it should be very easy to shoot, as easy to conceal, and may give me a little more punch. It is in the mail as I write this, and I will post my range results shortly.
These 3rd generation S&W pistols ended production in the early 90's, and are selling for under $400, which is substantially less than most of the current offerings. They are also metal, which helps reduce recoil and altho I intend to keep my G26, the 3953 is my daily carry.
It seems that if you wait long enough, everything comes full circle. I bet dollars to donuts that it won't be long before we see a revolver craze sweep the industry...and that would be fine with me. It's not about firepower or magazine capacity: it's about putting your round where it counts. And revolvers or DAO autos help me do exactly that.
Comments on DA/SA versus DAO
I own and have practiced with semi auto guns having all the common trigger arrangements. I have to agree that the DAO system does have advantages, such as avoiding the double action to single action transition. It is difficult to go from a 10 pound DA pull to a 5 pound SA pull while keeping all your shots on the target. It requires some practice to master this maneuver.
As the OP said, the Glock has one of the best DAO triggers - a constant 5.5 pound pull so that every shot feels the same.
