Sir, I did a search and came up with this from 3 years ago, PBFitz will likely not respond. You may search past discussions further if you'd like. Also available is the "Need help with your BENELLI firearm" which is the first pinned discussion, good luck!

From 2023: PBFitz Posted November 3, 2023 Hello All - REMARKABLE totally helped me with this. My trigger system was totally jammed - due to my stupidity- I did everything wrong.. and paid the price .. I needed to remove the steel locking plate (held in by the plastic locking block on the floor of the receiver) & once out, I could manually press in the firing pin hammers manually. Once that was done, I could muscle the trigger group back into position and lock it back into normal position.. it does take some pressure, but nothing violent. Very happy for the support and guidance

Mounting the Match-saver can be an issue. Options are: 2-sided tape; quick but weak hold. M-LOK screws, work best but you must have M-LOK. I got mine from: matchsaver.com but there are options on Etsy for example.

Welcome to the BENELLI forum! I suggest, especially as a new member, including a sheet with your user name, date and price written on it in your pics. This insures that you do own the for sale items and is a legit sale.

I'm sorry, I do not own that model, hopefully remarkable will be along as he, and others are very knowledgeable.

I believe 2 is correct.

It flows much smoother with transmission fluid. YMMV

I found this article and video interesting and worthwhile though it doesn't exclusively feature the BENELLI M4. Take from it what you want and yes, I read AMMOLAND daily. https://www.ammoland.com/2025/11/manual-of-arms-for-serious-shotgun-defensive-use-video/

Has anyone else seen that BENELLI has released the newest iteration, the M4 EXT. It features a 7 round factory mag tube, a 5 position C-stock and comes in 3 colors. Looks like they listened to RX-ARMS on the C-stock. https://www.ammoland.com/2025/11/benelli-unleashes-the-m4-ext-tactical-semi-auto-shotgun/

I prefer a field stock too but it depends on use. The only real advantage a pistol grip stock has IMO is being able to be held and used sideways, that's where it shines.

A search brought up this comment thread: the correct thread pitch is: M8-1x60 I hope this helps!
