I bought a 9mm, had good results out of the box, except the front sight white dot took a flight in the first range session, no loss, I black them out anyway. It was reliable and I never had any trouble with the slide or magazines, though topping the mags off was stiff, not impossible and eased with use.

I liked the first one well enough to buy a second and had similar and reliable use through the first 250 rounds of FMJ and SD ammo. I now rotate them to keep the round counts similar.

No problems, no malfunctions and an adequate number of magazines and a couple of IWB holsters. It's a good back-up for a larger carry piece and a nice pocket gun for around the house, walking dog, etc.

Good luck in your choices!
