"The DA/SA system isn't difficult to master." [Gats Italian]
Its not too bad on a Sig, but that's about it, every other DA/SA is more difficult. (ie PPK, SW99, M9, etc). Of course if your DA/SA handgun has a hammer you can simply pull the hammer back and go SA all the way.
"It isn't getting anyone killed. " [Gats Italian]
Well if my first DA shot misses, it might get me killed.
"Don't like DA/SA? For whatever reason?" [Gats Italian]
I do like DA/SA, but gotta admit a pure striker fired pistol, ie, a PPS, a Glock, etc. can be drawn and fired more quickly/accurately than a hammer or striker fired DA/SA pistol.
And the first accurate hit is pretty important.
For 20 years the sea was my home, always recall the sun going down, and my trusty friend, a 1911 pistol, strapped to my side.
