Hypothesis Concerning the Sig P320

Military, police, and private gun users have seen problems with the Sig P320 series — which includes M18s — for years now, Laramie-based gunsmith Brian Dimoff told Cowboy State Daily in a July interview.
Dimoff did not immediately respond to a Monday morning voicemail request for a follow-up interview.
Dimoff said last month that he believes the issue is that Sig Sauer tried to design its striker system without infringing Glock’s patent of that same system, and so made an ill-fitting design that may slip over time.
The internal pieces are under spring pressure and a block keeps the firing action at bay. If the pieces don’t fit together well, they’ll loosen over time and be prone to jolts.
“If one part begins to slip off another part, it’s a matter of time before it moves all the way down and you’re going to have a striker hit the primer,” Dimoff said.
As for Dimoff, he owns a P320 and says it’s a “great gun,” but he’s had it both customized and tested to the point of comfort.
It’s difficult for me to see how any striker fired gun can be “great,” but I’ll leave it at that.
This is an interesting hypothesis. I’ve always thought (and have said so over these pages) that the problem stemmed from tolerance stacks and parts wear. He’s adding to it by saying the specific design was to prevent patent infringement.
I’ve also read that the project began as a hammer fired gun (they should have left it at that) and evolved to a striker fired gun. Because big army: “We want a striker. Give us a striker.”
