Gotcha. I've watched videos on that. Is it really a big deal to use a gun in single action mode for self defense? Im reading the trigger pull is 3.75 lbs where as its not ideal to go under 4 for home defense. Is it really that noticeable. I feel trigger discipline will be more important in this scenario.
While I think it's not a bad idea to just go whole hog and get a Shadow 2 as your first handgun if you have the means (it is arguably THE best out of the box 9mm on the planet after all). That said, you really do have to realize picking it that it was designed for experienced users and thus isn't going to be as friendly or kind to a new user; the single-action pull is light, and manually lowering the hammer into double-action on a live round after you load it (while not hard) can be unforgiving/dangerous if one doesn't know what they're doing or giving it proper respect. (It's not just chance that DA/SA guns that one has to lower the hammer manually are pretty few and far between; they're more difficult to operate safely than Decocker or DAO guns in exchange for the reward of getting a better/simpler trigger pull design.)
Theoretically, a single-action gun for self-defense isn't a "big deal"; however, for an
inexperienced user it could be a
huge, possibly
deadly deal... I could write a chapter on why a single-action gun for self-defense probably isn't a good idea for a newbie (i.e. from forgetting to swipe off the safety under stress to having a negligent discharge due to the light single-action pull, etc)...
If you're planning on using the S2 for self-defense in a home defense scenario you realistically should know that the safest way to do that will be manually lowering the hammer after loading, and then if SHTF, shooting from the heavier/arguably-safer double-action first shot... and being mindful that there is no firing pin block safety in an S2, so if you can manage, you're probably not going to want to drop it ;-)
I'm not saying don't get it... but, I think I'm trying to come from the point of view of like how I would if someone told me they wanted to buy a 1000cc motorcycle for their fist bike: it can be done, and it might not kill you, but you better respect what you're getting into.
Just my $0.02.
