I spent a lot of range time with numerous rentals before answering this very question.
I'm in that rare minority of shooters who started with strikers and migrated toward DA/SA.
My opinion of the Storm:
- The compact is a good size for carry -- subcompact is not that much smaller but I found it hard to hold and control well
- The trigger in both modes is quite good, not as heavy as others
- The decocker/safety wings on the side (yeah, not levers...wings!) are sharp and obtrusive and bite into my hands when working the slide
- The grip is slippery and hard to keep a tight grip on
Beretta sells their "Compact Carry" model which is an $800 version that addresses all of the above issues through aftermarket add-ons and mods. Not nearly worth that price in my opinion.
I was very close to picking an HK P30 variant for DA/SA, but the DA trigger is really heavy and the gun is very thick. But it was awesome to shoot.
I settled on the CZ P-07 and got it for a hair over $400. It's dimensionally almost identical to the G19, but the trigger (after smoothed out over a few hundred rounds I'd say) is much nicer to me than either Beretta or HK. DA feels noticeably lighter than HK and somewhat lighter than Beretta. It fits my hand beautifully, has been reliable for 3K rounds so far and is very pleasant to shoot. It's a fantastic value. It's not hard to take down, but more involved than Glock and others who've made it so simple -- on the other hand, you don't have to pull the trigger to disassemble -- just decock with the lever.
DA/SA takes time to get used to. The downside is the heavy first shot (downside until you're used to it!). The upside is a light, crisp SA follow-up trigger that no striker will ever quite reach.
I also believe there's a real safety advantage to being able to keep your thumb on the hammer when putting it into the holster. Tons of NDs happen at this stage. Yeah, booger hooks and bang switches, the safety is between your ears...I agree completely...but humans fail. A hammer is no guarantee, but when I'm putting it into my holster AIWB, that hammer is held down and the heavy DA trigger isn't going anywhere.
(If you do go with Glock, look into the "Glock Gadget", a small mod that basically allows you to do the same as what I just described above -- you can keep your thumb against the striker so it can't retract if the trigger is accidentally pressed).
I'm just not a Glock guy. They're reliable, accurate, affordable, etc. and so forth. There's no reason not to have or trust a Glock. They're just not my thing.
