At around my 400 round mark, which was today at the range, I noticed my magazine getting stuck before seating into the mag well. I would move the pistol around and finally I could get the magazine in. Happened a few times. I got home, inspected the pistol, went to disassemble the slide absolutely would not move forward after the takedown lever was initiated. I kept fiddling with it over and over and thought, okay I'll try the Glock method of disassembly, and pulled the trigger before trying again (triple safety checked before). Voila. Slide came off cleanly. Then I noticed the takedown safety lever on the FCU was just as loose as can be. Stripped the FCU and found this. The safety takedown lever snapped. All ammo up to this point has been normal underpowered range ammo. The part that snapped off is actually the piece that has contact with the spring so it can engage/disengage.

Larry Vickers and Ken Hackathorn have both said that "shooting to re-set" is the worst "training scar" of the modern era.
Glocks are very nice, but whoever first thought up this method of shooting did all of us a disservice.
And before everyone jumps on and tells me how much faster it is, please note that neither Jerry Miculek nor Rob Leatham use this unfortunate method of trigger management, and they are about as fast as anyone I know with a striker-fired pistol.

Hello Guys, I am new to this forum and just wanted to ad my experience with my p250 full size .45 I was at the range last week getting ready for outside spring shooting. up here we are indoors all winter. I holster mainly 1911's, but for idpa I use my 229 sas in .40 and last yr started to use the p250 as I found crazy accurate and comfortable once you get the trigger down. Anyways I have approx 5000 rounds through her and first time out of safe last weds. I all of a sudden had light strikes on primers. found the part on the trigger bar that hooks to sorta what you would call sear. had worn slightly and hammer was not cocking fully. I could find nothing on this. just some posts on first gen. pulled the FCU apart for a closer look. and found very tiny amount of wear on bar. put it back together. held outside of grip. pulled trigger while holding bar tight against FCU frame. and the end of trigger bar snapped of at sear part.
It is at sig now and they told me never seen this before. anyone who looks close can see this happening. great gun but kinda cheaply done in that area. just my experience.

My Sig 320 broke its trigger bar today at the rifle range. Same failure. I have a very low serial number. Wonder if this was an early problem. I'll post a pic if anyone wants to see it.

Is the trigger bar in the photo made with layers of thinner sheet steel, spot welded together? The photo makes it appear so, and the break is at one of those spot welds. This introduces the possibility of contaminates or some other factor causing embrittlement at the weld.

Especially the first photo the "break" leads me to believe a batch of bad metal slipped thru the manufacturing process. It would really be hard for SIG to catch this, if that is what it is. If this problem intensifies, SIG may have to change metal specs or suppliers if the specs are subject to compromised.

My broke last week. I had 1200 rounds through it. All new brass ammo, mostly 115 gr. My P320C was manufactured in Jan 2017. My LGS was going to send the gun to Sig but they just sent them the part. Seems like a very fragile gun.

I sent mine back to Sig for repair, had it back from them in 7 days. Just put a couple hundred rounds through it yesterday, no issues. Hopefully they've identified & corrected the root of the issue.

I'm just thinking out loud here. But I wonder if there's more pressure on the trigger bar than what is assumed. I mean the force that causes trigger bite is being transmitted somehow. Maybe it's beating up the trigger bar too. I'm no Sig armorer, just taking a wild guess.

That part should never break in my opinion, Sig needs to figure out why that's happening and get it fixed especially since that part cost $60 to replace:
Sig Sauer Trigger Bar Spring - P320/P250 - $59.95 - Top Gun Supply
With the Army contract, I'm sure Sig will have this issue resolved if not already.
