Excellent. The 43 comes with 2 mags, one with a pinky extension, the other without. I prefer the mag with the extension. Have replaced the mag floor plates with Pearce +1 extensions which are nearly the same size as the original extension but gives me +1 in the mag. I have smallish hands so it feels great. Shoots, feels and acts like a bigger weapon at the range. Has proven to be quite accurate for me even though I'm not a great handgun shooter. As for carry, with the High Noon IWB holster at about the 4 o'clock position, almost forget it's there. In warmer weather in south Mississippi, I'm a shorts and t shirt wearer which can be challenging. LCP in the pocket on those days which is 6+ months a year.
