hmmm, I thought I had it tightened down, but I can see how this is about the only way that carrier could be hitting that shelf. I'll clean her up and ratchet down that mag tube and see if I get a different result the next time out. Thanks guys!

So I've had my 930 since '09 and absolutely love it. While everybody else clears FTF's & FTE's during matches, I've been lucky and my 930 never fails. For the last couple of years, I've only run light bird & low recoil slugs without a hitch Today, I went and did some clays with my son and we ran about 240 rds through it and my luck ran out . . . it had failures to eject 1 out of every 4 rounds or so. It would partially extract (shell pulled out, but still hung up on the extractor) or in some cases, the shell stayed in the chamber. . . . In tearing down the gun this afternoon, I found metal shavings hanging from the flat area where the mag tube comes in and shavings on the front of the bolt carrier where it appears to be impacting that 'shelf'. . . . . I'm hoping someone has seen this before or has any clues on what might be causing this?

Of note, I've since gone to 1x on my TR24 instead of the offset sights. I kept getting buggered up on weak-side stage setups. Still prefer my old TA33 though, it outshoots the TR24 at 200-300 yard stages all day long. If anyone wants my pair of cheap amazon offset rail mounts, I'll give'em to you, just pay for the shipping and I'll send them out to you. Alternatively, saw these on amazon as well: http://www.amazon.com/Front-Degree-Rapid-Transition-Backup/dp/B006X9DLQM/ref=sr_1_7?ie=UTF8&qid=1360704848&sr=8-7&keywords=offset+rail

I'm in the same boat, don't want to finish off my .223, so got a 522 for the short stages in my local matches. Now, I can't find any .22lr either, real bummer.

Thanks for all the advice guys. Got it resolved. Had to take both of your general recommendations to make them work: 1. Dremel'd and sanded the inside of the grips until the new K9 mags slid in smoothly 2. After number 1, found that they would not seat high enough for the mag catch to kick in. Took 7mmb's advice (thanks!) and sanded the top of the base pads as well and now I'm golden . . . Thanks again!

Thanks for the replies guys. As to the small / large frame topic. The Witness Match only comes in large frame . .. right? I'll try taking my grips off and see what happens.

This is probably a dumb question, but I'm stumped. I've got a Witness Match 9mm from about '09 with three of the original mags and it runs great. Never had trouble with the original mags and they drop free. Last week, I thought I'd get another set of three from EAA as backups. Called EAA and they tell me that the model 101935 (EA9M2005) 17 rounders are for my gun. Got them in on the weekend and they don't fit anything like the originals: - VERY tight into magwell, have to force them in - Removing a mag requires prying them out - slide doesn't seem to rack smoothly Although EAA tells me I have the right mags, I can't use these. Can anyone verify the model of the new mags by any chance?

The mids in 14.5 can be a bit gas sensitive. I've done both DD and BCM CHF barrels in mids and the BCM version appears to have a bit more gas / larger port. Both work well and are great products. Depending on what you shoot and your config, you may want to weigh that as well / larger gas ports = wider range of ammo. Of note, if you are serious about the Mid length, my experience has been that 16' gives you the benefits and may be more optimal (at least in my limited experience). If you only run 5.56, then either is fine, if you want .223, I'd strongly consider BCM and 16'.

I've got the PRI QC comp on mine and it works well and has almost no concussion back to the shooter, with a bit less concussion to bystanders. On the same rifle, I've had the JP Cooley and the FSC556, I prefer the QC as I found the concussion annoying after a while and on the FSC the regular bits of unburnt powder on my support arm was distracting. Maybe I'm a pansy, but I've found the QC effective as a brake and pretty good at keeping the noise from being unbearable. Additionally, it's pretty well priced and light . . .

Thanks NJD. I called Mossberg and their tech seemed pretty familiar with the scratching issue from the spring tip. He said they'll take it right back and correct it, but he mentioned that it had no functional impact. Well, saw your post, took a pointed round file and did some minor filing on that tip and problem solved. Took it to the range today and it cycles great (just like my SPX config has for the last couple of years)

got my '24 non ported barrel yesterday and found that I had this as well. Scores the mag tube all up, seems that the tip of the spring sticks out just a bit and digs into the tube. . . . really bummed that I'm going to have to send it back. Tried the tip from above, wood dowel from Lowes, and no joy. The second recommendation mentions loosening the spring nut, it's not budging and worried about scratching that all up and messing with my warranty.

Sweet,thanks again guys!

Thanks RAS and Nuke . . . one last question, does anyone know what size these screws are by any chance?

Gang, Just received my 24' non-ported barrel today and I've started the conversion of my SPX. Dumb question, but what are other SPX owners doing with the holes in the receiver when removing the rail? Wondering if there are any OEM-ish screws that will work?
