Hi Impact. I don't know any IPSC guys who replace/tune the lifter spring. I did try shortening mine thinking it would make loading easier & all it did was introduce some unreliability. Leave the spring alone. As for mag springs, people use custom springs because of the added capacity in an extended tube. The mag springs job is to reliably feed the first and the last round from the mag tube, so long as it does that it's good. Mag springs do have a lifespan are a service item. The best upgrade to make reloading better is practice, practice & more practice.

Do you feel you *need* a Comfortech stock? If you do, you'd probably be best to sell what you have & buy what you want. If you don't, then a decent recoil pad should give you most of the benefits for only part of the cost.

It's just a standard drop lever with a bit of metal welded onto it. You should be able to find someone local to weld it up for you.

Last weekend I was able to try a 1301 Comp, a 1301 Comp Pro & a Versamax back-to-back. I'll focus mostly on my impressions around the Comp Pro: Lifter remains "raised" during loading operations. This is a definite benefit during loading, but you can also mod the Comp lifter to do this. Loading port. Not bad at all, but I would recommend this being opened forwards more. Loading deuces, approx 50% of the time the second cartridge got hung up on a lip - this would need fixing for me. Stock with recoil mitigation and comfort enhancements, probably the biggest change from the Comp. In short - it works in reducing the recoil at the cost of *slightly* increased muzzle flip. For me, the trade off of flip vs. recoil would be worth it. If I already had a Comp, would I chop it in for a Comp Pro? That's a tough call but probably not. You are looking at a 50% increase in cost (UK prices) for maybe a 15% increase in performance. And the Versamax had less recoil & flip than either the Comp or the Comp Pro.

Bolt assy's are over $500 here in sunny England. Some people think it's worth the cost.

It's meant to remove 'Benelli bolt bounce' leaving the gun unable to fire. I have seen it fail though.

My honest advice to you is go shoot your 870 & form your own opinion. Your technique will be different from mine as we are different people. What works for you, may well not work for me and vice versa. Good luck amigo!

Found the thread just by blind luck !

Holy thread resurrection, Batman !!!!! I wouldn't go much further forward than that at all, you do meet a point of diminishing returns - more isn't always better There is a 'step' on the inside of the receiver that retains the follower. Grind too much of that out & your receiver has just become a paperweight.

Hold on to your hat, its $440 ! https://www.midwestgunworks.com/page/mgwi/prod/83201

I've heard people say that is indicative of a new lifter spring being required. Hope that helps.

My experience has been with a 930 waterfowl - Polish the shell stop so it reliably releases sells onto the lifter & swap out the hammer spring for a Wolff 10/22 extra power, to prevent light strikes.

You need the services of that well known gunsmithing firm - practice, practice & practice Seriously though, just make sure it fits you and then run it like you stole it. Alternatively, Red Neck Tactical may be able to help you....

For the sake of $100 - get it. That $100 will be dwarfed by the ammo cost over the lifetime of the shotgun.

Not yet. Don't have that many rounds through it yet, maybe 500 so far. Which part? The back end where the hammer strikes it, or the front where it bottoms out against the bolt? The back end where the hammer strikes it

Swordfish - has the head of your firing pin mushroomed?

Insulating tape (works on my 870) or nail varnish

Checkout the OR3GUN site, some cool reliability enhancement stuff for 930s. I'd definitely advise their marine spacer tube http://www.or3gun.com/OR3GUN/about_or3gun_marine.htm even if it adds no reliability (and I think it does), it should help prevent/slow down the rusting of your mag tube. I had a 930 without an MST, never shot it in the rain & still had a rusty mag tube. My go-to choke is Mod. I change that to Cyl for slug & buck.

Ask and ye shall receive........... https://www.youtube.com/watch?v=9Egeq4nbwKE I scored a 1301 last week

This is what I would do if she wants an 870 or a Mossberg... Hogue reduced LOP stock http://www.brownells.com/shotgun-parts/stock-forend-parts/stock-sets/adjustable-stock-sets/overmolded-shotgun-stock-forend-sets-prod18365.aspx Top that off with a slip-on Limbsaver pad http://www.brownells.com/shooting-accessories/recoil-parts/recoil-pads/limbsaver-slip-on-recoil-pad-prod19578.aspx?psize=96 This gives a 13" LOP on my 870 and is comfortable enough that I can shoot 200+ rds a day with no recoil worries As a measure, I've got a Supernova that is uncomfortable after 20rds - a result of doing stupid things with motorcycles in my youth....

Here's my 870 loading port. No, its not rusty - don't know why it looks like that in the pics No, it doesn't pinch my thumb No, the rounds don't fall out the side No, its not as quick to reload as my Supernova - but there is not much difference and I do prefer shooting my 870.

Apologies, I thought I had already replied to this. After checking some exploded diagrams, the Supernova safety is a totally different beast. Its located in the same place as a Vinci but that's all they have in common.

Does this fit a Supernova also?

Check that there is no binding on the hammer plunger, nor any binding on the firing pin. I've got a Supernova in the cupboard, so if we ever meet up you can certainly try my trigger group & see if it makes a difference. Roxy - as Michael Flatley & his feet of flame said, slug in the UK in not in great supply and when you do have it, finding somewhere you can test it is even harder.

Was that at Shield? I've had numerous light strikes with my Mossberg 930 on S&B slug from Shield - it's been fine on birdshot.
