This is a post designed to help people who are considering a firearm that fits this genre. Self defense/combative.
I remember my first Benelli like it was yesterday. Back in the late 2000s, I snagged an 11707. Immediately I bought an OEM mag tube from Numrich and installed it. I was murdering milk jugs at 100m with it with slugs, and mulching brush with buck and bird. This was back when the CB05(?) stuff was around. 12 copper plated 00 pellets at 1290fps from 2.75" shells. The weapon would malunfunion near the end of each tube. I figured it was a spring issue. Dropped in an m1s90 police spec spring. Issue ceased. Then came my desire to seriously use the gun. I needed a light. There was just no way to affix one, really. The surefire handguard either wasn't out, didn't fit the barrel flange of the 11707 models, or whatever, and LED lights were in their infancy, with Malkoff being the only real solution on a modded 6P.
Begrudgingly, I left the platform and bought an ar15. I could put a light on it. Optics were also more available, as I remember, we were stuck with the LaRue shredding split rail and minimal options other than LaRue or SWAN back then. I destroyed a Pride Fowled rds mount like that.
Then Kip Carrier entered the scene. Rails, full 1913. Ti mag tubes. Proper springs. Still no great light mounts. Then AVA tactical introduced a viable solution. As did Fab Defense (?) with their wonky little 1913 section on the sling groove ring. Things really hit full stride with thr IWC mounts. Scalarworks SYNC optic mounts.
I played with the benelli m4 off and on over the last roughly 1.5 decades, but only around the late 20-teens did it truly become a viable, cohesive weapon system, and I absolutely love my m4 Entry gun.
Time marches on, though, and MFALs, thermal, nvds, etc have become a thing. Once again, I have moved back to the ar15 carbine platform. I can mount my mfal, my light, an lpvo, a piggyback nvd compatible rds, etc.
I am excited for the day when we integrate this stuff into the gauge. I have already tried with a Surefire xvl2irc on an IWC light mount 1913 section, it just didn't pan out.
