well ill add my 2cents
ive worked on or built up into "tactical or defense" about 1000 870,s over the last 20yrs.
Yes the quality is getting worse, evne the police 870s, they is just not the attention to detail, the finish on the last 3,4 870 police I got was very bad.
With our custom built shotguns, we now just use the express and built from there.
At one point is was time saved buying a police and building from there, but its just not worth the extra cost.
The 870 is still the best pump action platform to build on.
We do so much work to them, that its not worth buying a police modle.
The truth is the 870 is not good out of the box, it need for 2-10hrs of shop work to make it a gun that you can depend on.
Many do not see the worth in this, some do understand that the 870 is the pump gun you want when the #### hits the fan.
this is what we do when we build custom 870s
Strip complete gun
Bead blast
Parkerise Mil spec Maganizse phosphate
Debur and police inside of receiver.
Polish and true but block up area
Clean polish and true ejector slot in bbl
3 stand chamber polish ,fine, extra fine and select grade polish
police exstractor.
timiney hammer spring.
Jumbo safety
No jam mag follower/delrin.
polish bolt lifter plate/
debur and dry film lube the pump forend metal
Polish and dryfilm bolt carrier.
Re finish complete gun in KG gun kote.
that's whats needed to make the 870 a good gun that will last 2 lifetimes.
After that you can start to add stuff like side saddles, sights sling and other crap as wanted/ needed.
