My experience was similar enough to the OP's that I will just hit the highlights.
I couldn't shoot the gun well at all. I do fine with my Glocks, acceptable (but barely) with the LCP, almost as well as the Glocks with the P238, really well with my BlackHawk .45 and my Single Sixes, really well with the 6" 686 and the 4" GP100, but not the LC9. The grip was too small, the trigger pull was long enough to make me think of packing a lunch and pretty much like dragging a rake across a skating rink waiting for it to grab on to something, maybe, if I got lucky. In the contest for worst trigger I've ever experienced.
A nit but a constant irritation was the butt ugly loaded chamber indicator. That thing is about as ugly a design feature as i've ever seen. The ones on my Glocks are just as effective and a heck of a lot less ugly. I bought it knowing about it, but I never liked it.
The gun never failed to fire and never gagged on any ammo I put in it, but that wasn't enough. I needed to be able to shoot it accurately and after close to 500 rounds I gave up on that and sold it taking a big loss on it. I really regret trading my PPK/S in on it - the PPK/S was a much better gun.
