I've got a P238 that also isnt working like a SIG usually does. If I make it through 2 mags without a stoppage, its a wonderment. Then again, its really not a SIG design, and its got most of the shorter than Commander length 1911 issues. I should have taken my own advice, and passed. Oh well, doom on me.
Mine was made/dated 5.19.2010, came with a mag with a "rounded" follower, bought a new one with a "flat with dimple" follower, Wolff replacement springs (cant get the SIG springs). So far, nothing seems to work. I've got around 700 rounds through mine now (in about three weeks time), failure to eject, failure to fire, tearing up 5-10% of the brass that does make it out are the symptoms. Add to that, a safety that makes as much noise as an AK or M1/M1A, and has the age old SIG slide stop issue (in reverse), have to replace springs every 1500 rounds (SIG manual), or 1000 rounds (SIG CS rep on phone), I'm REALLY thinking, what was I thinking? ( Well, I wasnt, thats the problem)
Maybe if SIG had copied a Seecamp, it would have been better off. Or better yet, come up with their own gun, something on a downsized P230/232, and one that works. All we have here is, another 1911 copy that doesnt work.
Heres a couple of my stoppages...
As for some of the others...
The P239 is basically as big as the P229. With a gun as big as a double stack, might as well have a double stack, and have the extra ammo. While youre at it, might as well go with a P226, since its only a skoshie bit bigger than the P229.
Skip the "little" or ""littler" 1911's, unless you want to go completely mad. Pretty much skip anything that doesnt have a "Prancing Pony" on it, or "Property of...." too.
Out of everything listed so far, I agree, the P7 is the one. HK should have stayed on these, they are one of the "great" pistols.
