mach1soldier Posted December 30, 2016 Share Posted December 30, 2016 I took my 9mm mpx out and had blown primers. Same reloads I use in my glock / 1911 without issue. The firing pin punched all the way through. Gun issue or ammo issue? Link to comment
Aircooled6racer Posted December 30, 2016 Share Posted December 30, 2016 (edited) Hello: Try some harder primers than the ones you are using. You using Federal perhaps? Thanks, Eric Edited December 30, 2016 by Aircooled6racer Link to comment
IntenseImage Posted December 30, 2016 Share Posted December 30, 2016 This is a new one. I'd give SIG a call on Tuesday Link to comment

3guns Posted December 31, 2016 Share Posted December 31, 2016 Shot my MPX today with S&B primers, no issues with the primers. I'm interested in what the problem is. Keep us informed. Link to comment
CZ85Combat Posted December 31, 2016 Share Posted December 31, 2016 Did you change the trigger/hammer or springs? Link to comment
mach1soldier Posted December 31, 2016 Author Share Posted December 31, 2016 100% stock. 150 rounds down range Link to comment
Neomet Posted December 31, 2016 Share Posted December 31, 2016 Yeah.... call SIG. No stock firearm should pierce primers. I'd say measure your firing pin to see if it is out of spec but I don't know for certain what the correct length should be. Link to comment
