When I range-tested my recently acquired Remington Nylon 66 [ http://www.taurusarmed.net/forums/o...-torn-between-two-semi-22s-7.html#post4654434 ] I took my Sig Sauer P250 along. When I bought it, it came with a .40 S&W barrel and a .357 Sig barrel. I had previously shot many rounds of .40 S&W and trust it to the point that I use it as my daily carry ammo. Due to price, however, I held off on buying and shooting .357 Sig until last weekend.
I bought a 50 round box of Sig Sauer 357 Sig 125 grain full metal jacket.

Out of 27 rounds fired, six of them failed to fire on the first attempt. That's a 22% failure rate!
Since the Sig P250 is double action only I was able to pull the trigger a second time on the faulty rounds. All but one of the them fired on the second attempt.
That one failed six further attempts. At that point I kept the pistol pointed down range for about 30 seconds, in case of a delayed discharge, before ejecting it. The primer was dimpled the same as other ejected shells, so I do not attribute the problem to a worn firing pin or weak spring.
When I was done shooting, I looked again at the faulty round, thought, "Why not?", loaded it in a magazine and tried one more time.
BANG!
For the record, I have never had a fail-to-fire in many hundreds of rounds of .40 S&W in the .40 barrel. Lest anyone wonder if the chamber on the .357 Sig barrel may be at fault by seating those rounds too deeply, the primer dimples on expelled rounds were all the same depth as the .40 rounds.
I bought the Sig ammunition thinking I'd stay brand loyal, just for chuckles, and also I have heard the Sig ammo is high quality. I'll try some other brands in the future, but until then I'm sticking with .40 S&W ammo for carry and home defense.
