Colt M1911A1

While some say you can't get as good a trigger with Series 80 vs 70, I think the bigger issue is additional (small) parts that could break. I had that happen on the on Series 80 I have - the arm of the upper sear lever broke and rendered the gun inoperable.

I replaced the (cast) factory parts with better quality aftermarket TiN coated replacements.

No problem since, but I'll stick with Series 70 & extra power firing pin springs - if I were to buy another 1911.

I'm not fond of titanium FPs, but to each their own - the heavier FP spring does fine for me.

Mine has performed with no issues.

Do you know of some problems with them?

Yes.

Light strikes - so a heavier than normal mainspring has to be used to ensure ignition, usually a 28# instead of the regular 23#. Primer extrusion, allowing the primer cup to flow back into the FP hole and eventually jam the FP. Crystallization of the FP over time causing breakage - mushrooming or bending has been reported when Baer used them. The FP tip is pretty much toast if a primer gets pierced, as titanium burns.

Now, many folks use 'em and never have a single issue with 'em. Me, I'll stick to steel - I don't need all the potential downsides of titanium just to help defend against the singularly rare event of a dropped pistol (which I've done my best to mitigate by using a heavier FP spring anyway). The fact that they're most commonly fitted by manufacturers just to aid in passing Cali's "drop-test" requirements doesn't endear them to me any more, either.

Interesting - thanks!

Don't drop one. Hey, maybe that's what the lanyard was for.
