I have a question about over pumping. This thing really likes RWS Supernags at 12 pumps. We're talking nickel size groups at 20 yards with a red dot. Am I going to hurt anything going to 12? I've got a scope coming for it but don't have anything that really fits it well at the moment. I'll do some better testing when it gets here.

If so, I have slightly bent them at 20 pumps. If you don't want to worry about it you can get a piece of 1/8" oil hardened drill rod and cut it to the same length as the factory pin. It works really well and has held up in my 1977 to twenty pumps for over 600 rounds. For that matter you can use a cutoff wheel in a Dremel and cut the shank off to length of a 1/8" drill bit. If you do that, I would believe you would be safe to pump as much as you want, but valve lock would be your next issue if the pump can build that much pressure. If you hit 12 FPE I will have to get one to tinker with.
I bet one of Ron's trigger mods would be nice in a 35 also.

I got tracking on the carbon fiber tubes I need to finish this build and it looks like it's going to be the middle of February. :'( Oh well, I want this thing to be all that it can be so I guess there's no sense in rushing it.

I've done the carbon fiber shroud mod to a 1977. You may need to lightly sand the inner tube to fit in the outer tube. You may also need to sand the bottom of the tube as it approaches the valvebody so it does not wedge between the barrel and frame. I had to sand a pretty good flat on the cf shroud before it would slide on the frame without wedging. You will also need to figure out a good way to attach the cf shroud to the frame. I bedded the cf shroud to the front bracket on my 1977 that uses a handguard mod. I have not devised a way to do it yet with the factory forearms. I tried a screw through the frame to a nut epoxied to the cf shroud but that wasn't strong enough. I have a few ideas but I have too many projects ahead of that one.
I've read some complain about how short the 35's stock is. Will an 880 stock fit? Is it plug and play or will it require some tinkering? Edinga has got me curious about these. I'd do the 880 barrel swap.
