[Pull & Mark]

You have already been told by the CG gunsmith what you should do.

I can't see what harm a little grease can do, if you wipe it off after each use. In 9 months the oil alone should be fine. The CG smiths will clean-up any grease inside the receiver during your first pit stop!!! Its your thumb, if it hurts after shooting do what you need to do. Otherwise stick with the Oil, if you can!!! break em all jeff

No disrespect to Pull & Mark. As I stated the oil didn't help. I was hoping to hear from other folks that have Guerini's and if they had this problem with their gun when new, what if anything they did to alleviate the issue or just kept going as is and
whether or not it "wore-in" and the issue went away in time.

Just make sure you don't grease tang, interference angle cut if you grease will bind

 

[traviszam]

This is interesting. What you refer to as the "tang" and not to grease is what I refer to as the barrel lugs and is the area I have always greased with other guns and greasing this area with the Guerini helps. It seems in my case, the bolt is what's binding in the barrel lugs.

You ask for our opinion, and when I give it, you don't want it!!! Did you totally miss the part I told you to grease it lightly??? Then wipe off the used grease when finished shooting for the day. Since the grease will be full of grit!!!
I would follow what the CG gunsmith told you to do. Regardless if it helps opening your shotgun or not. Yeh, most all of us had to break in a shotgun before. Tuff it out!!! The Action will get easier in time.

Your bottom lug is the same as any Browning. break em all jeff

Sorry about the incorrect nomenclature. The picture does ID it well Barrel Lugs.
This Picture I posted Came from Steve R from Target Shotgun, I had the same issue with my CG, As I always brushed a slight coat of silicone grease with my Browning's
, well I stopped on my CG, and problem has not returned. I purchased New last Aug 2020 from Steve at Target Shotgun, Thanks Steve R

I have 2 CG.. Unsingle & O/U. I never grease the area being described. I run a Qtip that has a drop of Rem oil through the area each time when I finished shooting. No problems with the lever being tight.

 

[Bossbald]

I should have mentioned that my O/U is relatively new with approximately 2 flats through it. Again no problems with the lever being tight.

I was told by a Browning authorized smith that is ok to grease the barrel lugs for an extremely short amount of time on a brand new gun. Say less than 500 shells, might have been only 250. Clean it welleverytime you shoot and refresh the grease up to the limit. The Guerini uses a similar design.

However, I was told to stop greasing the lugs as the locking bolt is designed to seat and wear. I'm not a gunsmith and take the info for what you paid for it - nothing!

Check you're not piercing the primer of the shell. My Summit trap was doing this when I initial received it using certain shells.

 

[SteveS1965]

seems you don't want the advice people here are giving you and you don't want the advice CG gave you, so i would just get a dremel tool and grind some metal off the barrel lug

What's with all the negativity? It seems politeness and respect have become politically incorrect on this forum. I value everyone's opinion. Thanks everyone for your input.

I’m new here and am wondering the same. I hope it isn’t common.
