for the 14" entry barrel you can do a search with the ATF the 14" barrel is for LEO/GOV use or FFL's. Unless youre one of those. Take it off your mind.

Always had a question about this... Magazine loaded, chamber empty, i personally put one in the carrier... Hammer cocked? or hammer down? Which one? Advantages to either?

Took your advice and installed it. Took 2 of us to get it in there for the first time. After a few minutes after being stalled i could tell it lightened some. 7 rounds loaded in there quite easily then. Not as hard as expected by looking at the size of the spring.

Anyone know the part number for which magazine spring to use on a M1S90 (tactical) with the 4 shot extension? Mag capacity is 7 rounds (of 2.75") I have a mag spring (benelli p/n 60479 - brownells p/n 301-000-115) but this thing is huge, and not easily compressed. I think its the wrong one..... Thanks in advance Mike

Old thread, I know, but how did you modify your stock to accept the recoil reducer? And im assuming youre using a Benelli 11oz one.... I have a M1S90 with pistol grip stock.
