I purchased a P938 (Extreme model) in October 2012 with a manufactured date of August 2012. First trip to the range was disappointing - multiple Failures to Feed, Failures to Fire, Failures to Extract and Failures to go fully into Battery all in the first 150 rounds using 3 different brands of ammo. I immediately called Sig customer service and they emailed a prepaid call tag to return the pistol within just a few minutes. In my cover letter, I complained about the stiff trigger in addition to all the failures. I dropped it off at FedEx for return on Oct 15th and received it back only 8 days later on October 23rd. The service ticket indicated that they: 1) Upgraded the Extractor, 2) Polished the Feed Ramp, and 3) Replaced the Sear Spring. I have subsequently shot several hundred (approximately 500) rounds including at least 5 different brands of ammo without a single failure of any kind. Also, they improved the trigger tremendously - it now has a measured pull of just over 6 lbs. and is very smooth. The P938 has now replaced my P238 as my carry pistol and I couldn't be happer.
