I just got mine. I haven't fired it yet and probably wont have the chance to do so for a long time. I tend to go for large heavy pistols and don't really own any other "small" autos, with the possible exception of the Bersa .380 which I never intended as a carry gun. So the P938 is sorta of new ground for me. I bought it without ever even having held one, so I really had some doubts, but the right deal just fell into my lap that I just couldn't pass up. Sometimes it just works like that.
So, without having fired it to really make a full review, I will still say that I really like it so far. I carried it around (mostly just around the house since it's untested) for the last two days just to get the feel of it and by comparison to what I normally carry.. it barely felt like it was even there at all. From a 2-1/2lb gun to a 1lb gun feels like an enormous difference.
Also, some have said the trigger weight was a little heavy, and I worried about that, but I was happy to find that the pull was quite acceptable to me. It's a little 'squishy' and maybe even gritty but not a particularly heavy pull. It seems well under the factory advertised specs. I did buy it slightly used though so maybe it's just been broken in to some degree. Worlds away and so much better for an SAO guy like me than any of the many DAO models in the "pocket gun" category.
