Agreed... I got the one from Wilson with the stud on the end, and it is solid. The Remington one just looks cheap... but completely based on pictures. Never saw one in person, so might be ok.
The safety is huge with a traditional pistol grip. The OEM grip... you can use with the Mossberg, but not a braced one. Pretty much, the safety is just left off in that setup. I had a JIC2 500, with Hogue pistol grip/forend, and that was a definite issue for me. I want to be able to engage/disengage the safety... not run it without anything in the chamber.
I originally wanted to get a second TAC-14, and do a rifle sight RMR combo. I liked my S/I folding brace, but heard some complaints about them installing traditional rifle sights on barrels... with it looking like ass (pictures I saw would never allow me to order one, but I’m also very particular with setting my guns up). I got the Remington barrel, but it is considerably lower than the ones on my 870 Police (higher than the bead... as I have a decent cheek-weld with the rifle sight barrel). Might just send the gun and barrels/grips out to Robar, NP3 Plus it all, then have a few options (I love the vent-rib look).
