I purchased this gun a few months ago and have had some issues with it at the range. First issue was reassembly trying to get the spring and guide rod to re seed but after some YouTube research solved that with the tricks suggested.

Secondly the mags were dis engaging while firing so a sig authorized gunsmith replaced the mag release assembly and spring and that seemed to help.

Third I am having some FTE issues which suggest extractor problems. You tube posts referenced this issue too and those who sent it off to sig said they replaced the extractor with an "enhanced extractor " what is an enhanced extractor ? I thought they all were about the same.

Gun production was early 2017 and I thought that most of the past problems were solved now. Anyone have thoughts on any of this please? Thanks.

I have a 2016 vintage P938 and have experienced no problems. While at the range I have observed others experiencing problems with the P938. After exchanging weapons it became clear the mag release issue resulted from a grip issue.
Don't claim to be an expert but I have observed an issue of placement of the thumb of the off hand causing problems.

Have to amend previous post, P938 was made 2015, bought a Glock 43 made 2016.

Mrsig27, I suggest you call Sig Customer service next week. They will pay to ship it both directions if they want it back. They may tell you to shoot it more to see if it continues to have issues.

I have put about 500 rounds thru it so far and it appears to work better with 124 gr or higher ammow and functions better with a 6 round mag as opposed to an extended 7 rounder.
