I'm told you can change a 2-3/4" to a 3". What's involved with this other than the barrel change?

I'm no smith, but I know the ejector has to be changed. A smith buddy did this on one of mine long ago, and he basically indicated it was easier to just buy a 3" 870.

IIRC, you would have to change the carrier and enlarge the ejection port. My suggestion is to trade the gun on a new one that takes 3" shells.

Well, there can't be ALL that much involved, because if you send your 870 to Wilson Combat for their "Remington Steal" upgrade, they will "Replace all worn and/or damaged parts, Convert to 3", Convert shell feed to flexitab anti-jam system, Install new spring and follower, Install new synthetic butt stock and foregrip, Replace safety with current design, Strip and parkerize all external parts, and Strip and anodize trigger group." And all for just $189.

This is not an ad for Wilson, just wanted to point out that since Wilson doesn't do ANYTHING for NOTHING, you seem to be getting an awful lot--including converting to 3"--for not a whole lot of money. This leads me to believe the conversion to 3" piece of it isn't all that bad.

To convert to 3", you need a 3" chambered barrel, and replacement of the ejector. Thats it.

I saw a slightly used 18" Express finished Rem 870 Mag with 7 shot factory magazine and synthetic stocks at last month's gunshow in PA for $180...

Is this a tactical conversion? The 3" has one hell of a kick with the slugs...

Dunno. Mine's surplus from the Michigan State Police and cost me $125.
