The only problem I have would be mag related. Mec Gar works best, I believe due the the heavy spring. I bought a KCI, or something like that, which has a substantially weaker spring and it either will not lock open on empty or will jam.
I like to avoid jams, as I've not figured out how to obtain the third hand that seems necessary to clear them.
They're like a match pistol in service pistol drag. Unfortunately with a service pistol trigger... It's good practice for trigger control, however!
I don't think that it's possible to regret owning one.
