Re: Mag extension for 930 Field??
Hi Ed!
I know the least about the S&J extension, I do however know one of the guys of S&J and know they sell some good stuff.
The Choate has perhaps been the most problematic. But I would say the issues seen are most common on SPX models in which the extension are fab or installed improperly.
The Nordic I feel (just my opinion based on reviews) has been the most reliable.
The mag tube design is the same from one model to the next and will accept extension equally and are interchangable.
As for installation, I couldnt say at all.
The 870 suffers problems I think because of a detent or notch or something that needs to be filed off when adding aftermarket extensions. Newer models may not even have that any longer.
