I have found no info on this anywhere. I have a fairly new (2014), but used, Rem 1100 Classic Trap and want try the Timney replacement sear/spring. When I disassembled the trigger group I found the housing was staked at the sear pin access, preventing removal of the pin. I didn't see any reason for it since the connector seems to secure it in place.

Is this a factory sear pin staking, and is there any potential problem caused by removing the stake? Thanks

I have not seen one staked in place, but they are normally driven in. I can't imagine aluminum staking to be much of a problem to remove it. You don't have to remove the sear pin to change the sear spring anyway.
Edit - Okay I see where you said you were replacing the sear, too.

Thank you and apologies.

I have been watching and learning from the forum for quite a while, but never posted. I shoot a wide variety of club-level sports, help the wife instruct new shooters, volunteer at the gun range and never met a gun I didn't want to modify.

Yes, and thanks. I can easily drill out the stake mark, it's really small. I just didn't expect to find it and thought I would ask someone before I break out the power tools.

I just today did that job on a couple of 1970's vintage 1100 shotguns. Neither of mine were staked. My only gripe is that the sear pin will only come out from one side, and you have to remove the carrier group to get to the side from which it much be pushed out. Getting the carrier group back in is a pain. There is a video showing a long bullet shaped pin that will help guide the carrier group pin back into place. All I had was a set of Starrett push pins, so cussed a bit getting everything aligned and back together.

Likeing lighter rifle triggers, I opted for the lighter weight spring, and ended up with a crisp pull just under two pounds. The timney sear does have an adjustable screw to add more tension to the sear spring, but I did not bother to adjust it. The sear does make the pull much crisper than my old factory trigger.
