My 2 cents...
The Fabarm Martial line of shotguns are available as:
Comp - Reg. Stock, no reciever picatinny, and blade sight on barrel $
Tactical - Reg. Stock, with same sights as mine $$
Pro Forces - PG Stock (mine as pictured at start of thread) $$$
Pro Forces Telescoping - PG stock with Knoxx style telescoping stock $$$$
I took the return spring out of both SG as it was more of a pain in the a$$ operating (insertion of shell through ejection port) and for "proving" safe at the range.
The old catalogue listed the 14" martials as 4+1, but now the catalogue indicates 5+1... not sure what changed. (if anything)
In my personal opinion, you cannot build up a shotgun like this (quality, looks, sights, short barrel) with a Rem 870 etc for the money you spend on these... and these look the best, shoulder, point, shoot, cycle better as well.
