Just purchased a new Sig P238. When a full magazine ( 6 round ) is inserted and a cartridge is attempted to be chambered, it jams. This happens when using either the sling-shot method or slide release method. Insert a magazine containing five rounds or less and no problem at all. I have only attempted feeding hollow points including Speer Gold Dots and Winchester PDX-1. If I insert a magazine with five rounds in, chamber a round, drop the mag, top it off, and re-insert, it jams again when the slide is cycled. I am guessing that it is some quirk with the magazine, but since it only came with one, I will have to wait until the extras that I ordered arrive before I can confirm my suspicion. Any other insight from those of you who own this pistol??
