Howdy folks. First post here. For me personally, the thickness of the pistol is the biggest factor for how concealable it is and how comfortable it is, more so than barrel length and weight for example. I am 6'4" and 195lbs. For guys like me with a slim build and no 'padding' around the waist to help hide the gun, a thicker double stack gun will print quite a bit more through light clothing, and is less comfortable for IWB carry.
It's why I settled on an LC9 for my everyday carry gun. In my Garret Industries Silent Thunder Fusion holster, my LC9 disappears under a light summer shirt, worn at 4 o'clock. I originally carried it in a N82 Tactical holster (original elastic style) but found the holster tended to move around more than I wanted it to, due to the single clip design. With the Garret IWB, it stays put, feels more secure, and is about 90% as comfortable as the N82 holster was.
Today I shot an SR9c for the first time. It was a rental gun at the local indoor range. I have shot Glocks (gen 2 and 3), and XDs, and I am not crazy about the triggers. I didn't expect the SR9c to be much better, being a similar striker-fired pistol. I wanted to find out if all positive the talk about the SR9c trigger was true or just hype, though, so I paid to try it alongside my LC9.
I honestly was shocked at how good the trigger was and how accurate it allowed me to be on my first go with it. No take-up that I could discern, short pull and a clean break. It was better than any other factory trigger on a striker fired pistol I have ever touched. In rapid fire, I shot much better with the SR9c on this first try than I can shoot with my LC9 after more than a year of practice with it. The only annoyance was that the range had lost or sold their 10 round mag for it, and only had the 17 round w/ grip extender. But I feel pretty confident I could shoot as well with the shorter mag that I would be using for winter CCW if I had one.
Honestly, it was Love-At-First-Shoot with the SR9c. I am going to buy the first new one I can get my hands on. As for my LC9, I am seriously considering the Galloway trigger mod to get rid of the take-up and move the break point forward. For my longish fingers, the LC9 factory trigger break point is awkwardly far back. I am not unhappy enough to sell it because I love the way the gun carries IWB and I can shoot well enough with it at social-work range, but I think for a house/truck and winter CCW gun under heavier clothes, I will be using a SR9c once I buy one. Plus the SR9c was just fun as a range gun and made me feel like a better shooter. That enjoyment will probably get me to the range more often to practice with it and my LC9.
But for the original poster who wants a single stack but doesn't want an LC9, I would look at the Walther PPS as an alternative. Being a striker pistol, it will be much closer to your SR9c trigger than the LC9 or Kel-Tec Pf9. I would say look at the Kimber Solo also, except for the fact that it needs to be fed premium defense ammo to function right (per the factory reps) and doesn't seem to like standard 115g FMJ which any 9mm should be able to function well with IMHO.
Anyway, good luck on finding a single-stack 9 you like.
