I've tried just about ever Compact 9mm on the market. Sig 938 Glock 26, S&W Sheild, Springfields EMP. XDS, Ruger SR9, LC9, Kahr CM-9 Berertta Nano, ect.
That being said, I keep carrying and coming back to the same two handguns.
1st, i absolutely LOVE my Springfield EMP 1911 9mm. Its very Accurate, reliable, fairly light, and it's a 1911. So, of course so I carry cocked & locked, like when toting any of my 1911's that I'm so very familiar with. They are expensive, but worth every penny in my book.
2nd is my little cheap Kahr CM-9. It's also EXTREMELY reliable & plenty accurate for a pocket sized 9mm. Main thing I like is it has a decent carry trigger, no saftey, and it's small enough to fit in the pocket of my Wranglers and not too heavy for discrete carry. And it has much better sights than all the ultra small 9mm's like the Ruger LC9 & Keltec 9. And a better trigger.
I will throw the Glock 19 in there, as I much prefer it over the smaller Glock 26.
I can conceal the Model 19 just as easy as the Model 26, + it has a better grip that fts my hand much better than the 26.
Not to mention 16 rounds vs 11 rounds.
Again, Ultra Reliable, and very accurate. And pretty easy to shoot for all the new CHL shooters I've trained, especially the ones with minimum or no prior handgun experience. Also plenty safe to carry IMO, if you follow the #1 and #2 rule of gun saftey.
#1, ALWAYS treat it as its Loaded, and #2, keep your damn FINGER OFF the Trigger untill you are ready to shoot, and your ABSOLUTELY sure of your Target!
Hope this was helpful, JMHO, though. And it's what I generally recommend to new CHL holders, if they don't won't to carry a revolver, which I usually recommend for a first time handgun owner.
