How come I got drug into this?
Ya'll got the answers already from the Folks more learned than I .
Anything can and will break.
Only absolutes I know about shotgunning - ain't any.
Hey I am the guy that had a sear break on new Krieghoff, 3rd round it ever fired and it broke, I bested that with a Beretta O/U, first shot attempted, and its sear broke.
870s.
-I personally feel the older guns are better due to metallurgy , how crafted and QC. Not just 870s
Dry-fired the living fire out of them 870s and never have I broken one of mine or anothers.
I have seen firing pins wear out, break, springs break due to a LOT of rds downrange and such. One such gun has over 300K rds thru it. It has been to Big Green 2 maybe 3 times for a "going thru".
I have seen frozen firing pins. We always kept a can of Zippo lighter fluid in the Duck Blinds, Duck Boats, Deer Stands...vehicle, ...folks would over lube the pin area, combined with grit, burnt powder and what have you getting in that channel...freeze up. Yes some have broken.
I / we dryfired a LOT. We also used homemade dummy rds with something in / for a primer....okay I admit, a lot of times we just left the spent primer in the shell reloaded as a dummy.
-New 870s.
Might as well get this out of the way.
The newer offerings are fine, I have tried to tear one up [folks that know me better understand that "try to tear up" part]. These bone stock 870s work, including the Express Line.
Even with all the Plastic parts, different mag innards, cap, no detent.
Except for the
J hook safety
-These new guns DO concern me. I have again observed the frozen firing pin/ and breakage. And the extractor. I may be in the South, still gets freezing and Duck hunters out in freezing temps - add wet- have the greatest chance problems. Old 870s seem less prone than new ones . Design change and material changes...I suspect.
Extractor is MIM. ADD the POOR Quality of "brass" - well it used to be - now recycled beer cans or something and it is not the chambers so much...friggin ammo is not to spec , not to spec with beer can "brass" to boot!
I'm getting to where I suggest folks do more and more dummy drills and use. Use a QUALITY hull - like an OLD AA [new ones just flat suck now they ain't compression formed) STS , Fiochhi ( lavender is a good color for dummy rds btw).
Folks need the drills - we always did them. Today with the metallurgy, QC, and such...well the drills with dummies is needed anyway - added benefit is having something for the firing pin to hit .
I mean dry fire all you want with new guns and no snap cap or dummy. Just perhaps folks need to do more dummy drills anywho. Might as well slap the trigger, if need Shuck - Repeat, loading and unloading, the whole bit. Part any gun becoming an extension of one includes Admin, and load/unload.
