Series 70 vs 80 for carry — does the firing pin safety matter in Minnesota?

The firing pin safety doesn't prevent a negligent discharge in a holster. The holster does that. What the Series 80 safety does is add mass and friction to the firing pin itself—it requires the trigger to be pressed before the pin can move freely. In a Series 70, the pin sits loose.

Now, here's what matters for your carry gun: that Series 80 system adds a perceptible stack to the trigger. You're fighting both the grip safety and that firing pin block. On a quality 1911, you'll feel it. Some shooters don't care. Others can't shoot it well because the trigger response changes.

If you're already carrying in a quality holster—and you should be—the Series 80 mechanism doesn't add safety. It adds trigger complexity. The holster is your primary negligent discharge prevention, full stop.

The liability argument is separate and real, but it's a lawyer question, not a gun question. Talk to your lawyer about Minnesota's self-defense laws and what carrying a Series 70 means for you if you ever have to use it.

Pick the gun that points naturally for you and that you shoot well. For most shooters transitioning from shotguns, that's a clean, crisp trigger. A GI-spec Series 70 is predictable. You can always stipulate in your carry insurance that your gun has been professionally built and tested. That matters more than which safety the frame came with.

jmb's right about the mechanical function—the Series 80 firing pin safety doesn't prevent ND in a holster. But I need to push back on the liability piece being "separate and real" without more detail, because Minnesota's framework actually bears directly on your carry choice.

Minnesota Statute 609.65 governs use of force in self-defense. It doesn't specify what firearm platform is legally preferable or safer-appearing. Your *carry holster quality* and *training currency* are what survive scrutiny post-incident. The gun itself—Series 70 or 80—is irrelevant to the statute.

Where liability enters: if you're involved in a defensive shooting, prosecutors and plaintiff's attorneys will reconstruct your decision-making. "Why did you carry a gun without a firing pin safety?" is a question, not a disqualifier. But you need a coherent answer rooted in *your* training or assessment, not "I read online it doesn't matter." That looks like negligence in hindsight.

If you can articulate—truthfully—that you trained extensively with a Series 70, that you've validated reliability through your own use, and that you carry in a retention holster that you've tested, you're on solid ground either way. Aftermarket Series 70 guns especially: document the build quality and shoot it extensively before carry.

Carry insurance (USCCA, ACLDN, etc.) covers the legal defense regardless of platform. They won't deny you over Series 70 vs. 80.

Bottom line: pick the gun you shoot best and train with relentlessly. Document your training. That's your actual liability protection.

Not legal advice. Talk to a Minnesota self-defense attorney about your specific scenario before carry.

Both of you are hitting on things I've been reading about, but I'm getting pulled in different directions on one piece. jmb, you mention "a quality 1911" and "aftermarket" in passing — I'm looking at some Series 70 conversion kits right now (barrels, springs, firing pin), and I can't find much written from people who've actually *carried* one long-term in Minnesota winter.

I've got plenty of shotgun time in heavy clothing and retention holsters. I know what a bad holster feels like and why OWB with proper coverage matters. But here's what I'm not seeing clearly: when you go aftermarket Series 70 conversion on a frame (say, a used Colt or even a 80-series frame modified), how reliable is that setup in the first six months of actual carry versus buying a purpose-built Series 70?

I've been reading that converted guns need more break-in, and some people say that's overblown. Others say it's fine if you test-fire 500+ rounds first. That's not a question I can answer from shotgun experience.

ctpistol, your point about having a coherent answer landed — I get that carrying a 70 requires me to have actually *validated* it, not just read that it's fine. That makes sense for Minnesota.

So: has anyone here actually run a Series 70 conversion kit through a full winter carry cycle? Or should I just hunt for a purpose-built Series 70 Colt and skip the conversion route? I'm trying to understand if "get a 70, train hard, document it" is different depending on whether it's factory or aftermarket.
