How do you figure it's cheaper? I get that the accessory market is heavily geared towards the 870 with the Mossberg 500 a close second. But an LEO grade 870 will be at least $300.00. If it doesn't already have an extended tube then that's another $60.00 plus shipping. I know because I already ordered a tube extension for another gun. Not that there's anything wrong with the 870 but I will probably never own one. I already have a Mossberg 500 which has much better safety and slide release controls. At the right price I'd probably buy one of the Chinese 870 knockoffs.It is cheaper to just get a surplus LEO Rem 870 with the extension already installed. Plus LOTS of aftermarket parts available for thr 870.
With the Higgins, you are putting a $500 saddle on a $20 horse.
Of course I would never try to go mall ninja tactical with this Higgins that's old enough to not have serial numbers and only shoots 2.75 inch shells. But I like having more than 5 rounds in the tube. My Smith 1000P that I cut down only held 4 rounds originally. So of course that was unacceptable. Now it holds 6 and I'm good with that. I only have $100.00 in this Higgins. So even if I paid the $75.00 for the KAK long tube I would still come out cheaper than even a used 870.
Better yet I have a deal going now for a ratty old Stevens model 67. I dig those ugly bastards cause they remind me of the 70s.
