Common sense SIG P320 spare parts kit
Tampa_Mark
Location: Tampa, FL
Date: January 15, 2026
- I recently was putting a lot of ammo through this new P320 we've had for awhile, but had never been "broken in".
- I experienced a catastrophic ammo case failure, due to an "out of battery
detonation".
- When the case blew out, the extractor blew out with it. Midwest Gun Works had not only extractors, but also spare parts.
- So I bought other parts that would likely be consumable over time. I'm very happy with their inventory of SIG parts, and their competitively priced, not to mention quick shipping.

Standard SIG parts. As a gunsmith I recommend this kit over the aftermarket kits. The aftermarket kit tends to use lighter striker springs to give a lighter trigger, but risking light primer strikes in doing so. If you want a lighter trigger, go to the SIG Sauer straight trigger and lighter sear springs and lighter trigger bar spring. You can get the light trigger without risking reliability.
