They're good guns and they're completely reliable. Don't know your required dress mode. The 6900-series is somewhat thick, and I find it "carries" larger than the otherwise-same-sized 3913. Smaller guns exist (even double-stack ones), and I generally find I need to use them with business clothes.
For me, with clothing that is bulky enough to make the 6906 easy to conceal, I find I can easily also conceal something bigger (like a full-size gun).
I would never suggest that this isn't a perfectly wonderful carry gun, it's just that the thickness and size may present an issue for you. Why not try this: wear the gun (unloaded,
sans holster if you don't have one) around your house while you await your license (provided that such is legal where you live

) and see how it works out for you doing the sorts of things you would be doing dressed in the clothing you would be ordinarily wearing with it. That will give you a better idea of whether the gun will work for
you as a carry piece.
Don't let anyone tell you that it's not suitable for such use, though: that's a great pistol.
