I know how hard it is to find old magazines for the model 104. So, here's a link that has some. I've never done business with them, but wanted to put it out there if you're looking for one (or more).


Original factory issue seven shot magazines. Mossberg manufactured 1949-1960, very good condition with 90% plus original blue finish.
Yes some magazines are hard to find. The original 144 magazine was a R498 which was later up dated to a R632. Usually fits a series 100 ie 152, 140, 142, 144
Has anyone seen any of the 15-round magazines which Havlin Sales sold a number of years (maybe 8-10?) ago?

Also, did the model 144LSA use the same magazines as the M44s?
My dad had one of those adjustable magazines for the 353T, and it would shoot shorts, longs or long rifle.

I don’t know what happened to it, because I didn’t recognize what it was, and is probably in the bottom of a box of old computer parts.

Anyhow, I’ve never even seen one of those offered for sale.
