Lots of development going on here! Looking good, SD!

Welcome !

I found it to be a decent lube and an excellent cleaner.

Well, did the ejection pattern change from before you used Froglube, to after? If it truly reduced slide-pull effort by several pounds when hand-cycled, it should have a VERY DRAMATIC effect on cycling when fired. Is recoil more violent? I just refuse to believe that a lubricant that isn't as effective at wear prevention as Mobil 1 automotive oil could produce the results you are claiming compared to what you used before. When the stuff came out, I thought of it as snake oil, then I tried it, used it, and still think of it as snake oil. I did run it for a while, though, and form opinions from actual usage.

How are people reducing the slide-pull on a pistol with a non-interference fit slide? Take the spring out of your P938? and then operate the slide. Chemically de-grease it, even. If it takes "several pounds" of force (other than overcoming the mainspring for the hammer)...something is WRONG! I tried the Froglube thing and went back to conventional lubricants after rust issues. Froglube is a decent barrier protectant, but does almost nothing chemically to prevent rust. I discovered that on my own "in the field". Had the bolt in my M4 get speckles of rust on the tail after 120 rounds, trip to a friends house where I wiped the BCG down, leaving a light sheen of remaining froglube on it, drove home, and after about 72 hours I broke it down again for a detailed cleaning and saw the rust. I had previously noted rust formation on the BCG by the gas-key, and in the barrel extension, as well, even though I heavily lubed with Froglube, the condensation from gun-scrubber (gets surface cold) apparently attracted enough water to rust the metal ever so slightly. When applied heavily on a chemically prepped/clean surface, Froglube works okay, but in the real world, for me, I have found that it sucks. I can run 1500+ rounds without cleaning through my M4's with Mpro7-LPX, anyway. I gave my Froglube away. *M4=AR platform for sake of this post.

The military tried a bunch of fancy solutions for the M4 BCG, but in the end, the old regular one actually performed better, and was cheaper, too, of course.

+1 for SOCOMguy and his product.

Yesterday I just watched over 60 cases of 7.62x39 sell out at sgammo.com in under 10 minutes.

No problem. Slugs are not just slugs. The fosters and their ilk do very poor on the penetration thing, until velocities drop, and then they have such a large frontal area and low KE/Velocity, that they still don't do as well as one might think. For deer and people and such, that's no big deal, but for large bear and things like that, its a fool that goes afield with fosters instead of Brenneke's or the equivalent.

Pushing those kinds of slugs that fast result in a frangible projectile. IF that's your goal, go for it. I used some of Winchester's HP slugs advertised at 1700fps or some such one time and they wouldn't make it through but about 1-2 milk jugs filled with water at 15 yards. Third jug was un-harmed. Regular fosters are almost just as bad. Drive them slower, and they penetrate better because they don't turn into a doughnut, but rather "compact" on themselves and expand radially a bit. I use standard velocity 2.75" 1oz slugs from Remington on the cheap, and Brenneke Classic Magnums when I feel spendy.

I tested it and Froglube did okay except in the corrosion prevention dept.

When was this spring manufactured? How old is your setup? You can modify Kip's older springs by cutting the coils. You will note on the older springs there are several coils "stuck together" on each end that are all "flat" in their winding, and removing all but 2 or so complete 360* turns of "flat-wound" coil on each end should solve your problem. This was fixed on later runs of Kip's springs. That being said, you may have found a shell that just isn't compatible. It's possible, as some shells are quite long even though they are "2-3/4" " See? Trim that CC spring to look like that OE spring... It will not harm function if you do it as I detailed, and it should allow that last shell to squeak in there. That spring is from 2009, and the image is courtesy of "Duggan". Kip has since revised his springs to be more like the OEM one shown, regarding the end, for the exact reasons you have noted.

I don't think anything is wrong with the photo. I am not a fan of Obama or his reign, but I'm not going to look for pixies in the garden, either. Was he shooting clays? Probably, who knows. However, yeah, this is him shooting a shotgun, and I would presume that he was indeed. I don't think it was shopped, etc. Face-value, here. Does he shoot skeet often? Who's to say? He well might.

My Mesa 6-shell carrier kept shooting loose, or I would torque it down until it temporarily deformed the receiver and it was hard to seat the barrel tang. I don't use it, anymore.

Correct. I don't run an OEM hammer, but I do have my old one. I looked at it and it does show a right-side wear bias similar to yours, as well as the polishing. I am guessing by the look of mine and knowing how few rounds is through it, especially before I swapped hammers, that your M4 is VERY low round-count as of that picture you took.

I would just leave it alone. Anodizing (IIIa like what we are discussing) is RC70, and very durable stuff. If it's getting peened, I doubt NP3 will fare much better. It might, but even if it does...so? Spend the money buying ammo and having fun training, or putting gas in the car for a month, or something like that.

Okay all, I know we spend good money on this weapon. It isn't a Hi-Point, and it isn't cheap. It's normal for someone who cares about their investment to worry at least a little bit, especially when you aren't familiar with the platform. I have been guilty of the same exact thing. I would advise before creating a huge thread, etc. though, that you go to http://www.google.com/imghp?hl=en&tab=wi and type in something like "Benelli M4 ejection port"...guess what pops up? Tons of pictures of them. Many from this very forum. They all have wear and tear from ejected hull rims. You can safely conclude "This is normal" as long as yours is somewhat similar. Anyway, I'm pretty dang OCD myself, and this has helped me chill out and not start a thread about something that is a non-issue before as well. If you still want to start a thread, fine, but this is immediate feedback with visual. Can't beat that.

Looks normal enough, as long as that isn't a chip I see on the hammer.

While I love my Benelli M1014, if I were buying a pump gun, it would be an 870P. Also look into the Burris FastFire 3. I had one and it was very nice. Just a thought, T1 is awesome and I run one on my M4 SBR.

Notice how the fronts of the ports in my flash-hider/suppressor mount look like sharp "V"'s? They used to be U-shaped. Metal has worn out of the "U" to make them a "V". HORROR!!!! Here is a picture I dug up of the same weapon when new, for comparison. Oh the horror!!! WEAR!!!! *FYI, that's a $129 mount that a $1460 suppressor lives on that would take another $200 tax-stamp and over half a year hung up with ATF paperwork to replace if something real actually went wrong with that mount, which, it's fine, just showing that it actually gets used. Stuff wears, it's cool, chill.

It can also become dirty from fouling, as well as a bit oily from the lubricant used to aid proper function. If you want it to remain perfect---don't use it. Here are a few pictures of a $2600 rifle I took to a carbine course. I babied it pretty well, I think, although I did jam the muzzle through some windshields, bump a few barricades, and the receiver spent a bit of time rubbing against my gear belt. That sparkly/sand-like stuff you see on the shot I took of the BUIS is shattered glass particles/dust from windshields and passenger windows. It still works, though, and I'm sure it's going to get the crap knocked out of it again during Street Fighter in a couple of months. Lots of work in and around cars, that course. These are a working man's tools. They will get scratches. They will get dings. They will still work.

There is no problem. All it would do is add unnecessary weight. When you find me a Benelli 7075 alloy receiver that has "worn out", please post a picture of it.

It's normal wear and tear within tolerance. Don't stress over it. Only stress over things that should NOT be there. Other stuff for you to look at that will drive you crazy... The barrier battering the back/inside of your receiver. The hammer-face being peened and polished. The linkage being scarred as it rotates in the base of the carrier during recoil.

Lube is the issue, as well as those shells having cases that I hear like to get stuck. Run it wet, buy stuff other than the Winchester bulk-box. I broke my M1014 and last M4S90 in on 2.75 dram skeet loads. Just lubed it correctly first and held it tight.

It is not damaged, and this falls under the category of wear. If you don't like it, sell it and don't ever buy another M4 shotgun, because I can promise you 100% that it will do it, too. I doubt you meet anyone near as OCD as me about their gear, either, so take it FWIW.
