Some of the people reading this know that I have one of these modular pistols in .40 S&W. You will also remember I have been having reliability problems with it. I think I found the problem. And it's something SIG should have replaced when I sent it to them shortly after buying the gun.

The first time I field stripped the pistol I noticed the unusual recoil spring. It is a coil of several wires coiled together, with a single wire making a turn and a half on one end. This wire went against the flute on the rear of the guide rod.

Last week, when I tried to field strip the gun, I discovered that this wire had slipped over the flute, and was interfering with the disassembly lever's operation. Greatly irritated, I started looking for a place to order a replacement. Found one, and the price was low enough I bought two.

The new springs arrived today. They are identical except that one end of each is painted blue... and there's no wire.

I'm now wondering if that wire has been the cause of my problems. And if so why SIG didn't replace that spring when I sent the gun to them.

I will test fire the gun with one of the new springs in place later in the week. If it functions perfectly, I will be *very* *angry* with SIG.
