I bought a pistol grip stock for a Benelli M4. Finally got around to trying to put it on and the trigger group will not seat far enough back for the pin to go back in.

I'm thinking I mistakenly got sold a M1/M3 stock.

Anyone have a similar issue going from the field stock to the pistol grip stock?

Or am I just dumb?

It's been a while since I switched mine, but I remember there being a lot of shitty knockoffs out there.  What brand is yours?

I got a Promag collapsible stock back in 2019 off eBay.  I remember a not-difficult installation.  They were discontinued and hard to find even then; as it was I paid $175 compared to the $129 retail price.  

Discontinued item at Midway

Freedom Fighter Tactical is probably the best place to get M4 stuff.

It was sold to me as factory benelli, and I believe that it is factory.

There are no model markings on it, which makes it hard to differentiate if it's for m1/m3 or m4.

Benelli sells both as different model numbers, so there has to be some difference, but i don't have a m1/m3 to test against.

Issue resolved, likely user error, though I did buy a 2nd stock to confirm dimension were the same. This can be locked/deleted.
