After reading this thread, I was pretty sure that the KT 380 was going to be my first pocket gun. However, found a freind that had one and took him to lunch and then the range to let me shoot it.
1. I'm not overweight but have fairly large hands and the index finger wouldn't fit well in front of the trigger. Had to kind of work the finger in. Your pictures make it look like the LCP may have a slightly larger index finger opening.
2. We were shooting reloads. Out of nearly 40 rnds, one FTF due to a raised primmer and about 10 FTE. Determined that all the FTE casings were split. Then noticed that another 5 or so that did eject were split. The primers showed no overpressure indications. We then shot my old Husqvarna WWII 380 and what I think I remember as a Khar with no split cases. Now I'm thinking the KT maybe has a slightly larger chamber than the others. Will be looking into this further.
