I shot it yesterday and had no issue with the trigger. DA is a bit much, but there is no way you can say it accidentally went off.. I think most of the online comments about how it is not useful in DA mode are mostly posted by drama queens that expect perfection out of everything in life.
After I put the hammer spring in, I could routinely hit a 6" plate at 25 yards off hand DA. I couldn't consistently hit a paper plate from 15 yards with the stock spring in it. It was a dramatic change for me so I guess I'm a drama queen.
Definitely not much of a pocket gun, though. I got a pocket holster and put it in my pocket, but it's pretty easy to tell what it is..
It's as thin as a PF9 and a lot thinner than my P11 that I pocket all the time, same height and only maybe a quarter inch longer in the slide. It is heavier, but not that heavy. I don't really worry much about printing, but it prints much less in a pocket than my Kel Tec because it's as thin as a P3AT/PF9. I think it works rather well in a pocket. I also like it in my Law Concealment Systems IWB pouch. The thinness of it makes it quite comfy IWB. Doesn't have the bulge of my revolvers nor the thickness of my Kel Tec.
Difference is really moot, though, as all those other choices I compare it to are acceptable to me for either pocket or IWB carry. I guess you could go long tail T shirt/polo shirt and OWB if you can't carry it any other way. Anything that fits a PPK should work where leather is concerned. I never did figure out why 007 carried his PPK in a friggin' shoulder holster.
You should try a 19 lb hammer spring in it, though. Hard to tell you how much difference, just need to see.
I was thinkin' it wasn't bad enough to mess with, either, but I'm glad I did. The 22 lb recoil spring mitigates recoil a bit, but the 19 lb hammer spring was the real improvement.
