Aluminium frames

    Hey all,
    I'm hoping to get a little feed-back regarding Sig frames. I'm very close to pulling the trigger and getting a new P22R. I keep getting hung up on the aluminium frames though. I've been stigmatized over the horror stories I heard when I was younger about the aluminium frames on Commanders. I had gotten to the point where I figured that if militaries felt aluminium framed guns such as the Beretta and Sig were durable enough to field there shouldn't be a problem. I then made the mistake of coming across a post on Sigforum that had a guys CPO 226 with rails that split right off the top of the frame.

    I keep reminding myself that there are always exceptions. Any gun regardless of manufacturer had the potential to fail catastrophically. I understand that a normal shooter such as myself may never come close to reaching the service life of a 226. But what keeps me hesitant is how frame wear has been explained to me. That is that a steel frame will wear and wear until it is just no longer usable, but an aluminium frame will wear to certain point but when it fails, it fails big.

    I've pondered getting a stainless 226, in which case it wouldn't matter. I'm just not a stainless person I guess.

    So I need input. I'm having a brain crisis over this. On the one hand I know they've only gotten their reputation as great guns because they've earned it, but I also have an ingrained fear of aluminium frames.

    Help me!!!

    There are dozens of threads on this topic over on Sig Forum; one of which deals with anodizing being worn through and damage to the aluminum frame.

    Personally, I prefer stainless steel for longevity and weight.

    I have three Sig classics with aluminum frames. Just keep the rails greased, and your good to go.

    No problems with the aluminum rails. Purchase with confidence.

    Plenty of guns today use aluminium frames. Even a lot of .45 1911's use aluminium. The strength and durability of todays aluminium is much better then it was 20, or even 10 years ago. Buy with confidence. I love my Sigs.

    Keep in mind that even steel frames have their problems also. Without proper lubrication steel frames can be more prone to gauling then aluminium frames.

    Whichever one you choose just use common sense. Proper cleaning and lubrication is all that is needed to ensure a long life for your pistol.

    I own a P220 with an aluminum frame, but I much prefer all steel.

    I guess it's a mental hang up. I know they are in widespread use, and they must be durable because lots of military and LE agencies use them. And the funny thing is I really want one. I'm just concerned that if I get one I'll have that feeling in the back of my mind that it's somehow "handicapped" because it is aluminium framed. It's absurd I know, but I tend to obsess especially when it comes to guns. What's even more absurd is that I keep feeling like there is someway I can convince myself it'll be ok. Do I have a problem? :therapy:

    Aluminum frame is ok up to 9mm, but steel is better after that. IMO.

    Dont forget that Glocks, XD's, HK's, and many others use a Polymer frame. And they are some of the most reliable handguns out there. Just because something isnt made of Steel doesnt mean its handycapped. There will always be people who say "Its steel or nothing for me". To me those people are just missing out on some amazing firearms.

    Also remember that when youre taking a vacation and youre on the flight to your destination, your flying in a plane mainly made up of aluminium. If you trust it with your life while youre at 30,000 feet, why not trust it while youre on solid ground. Just a thought.

    All Sig P226's, made of Aluminium or Steel, are fantastic guns. Buy with confidence. Sig stands behind their product 100% with a lifetime warranty to the original owner.

    It's the fact that aluminium is a fairly soft metal. The anodizing does harden it but the hardness is pretty much just on the surface. So when the anodizing is worn through it goes to hell relatively fast. Aluminum is a great material, but it's frictional wear property isn't even close to steel. And as far as polymer goes, the rails are still made of steel, so you have steel sliding against steel. I have no problem with polymer frames. If the aluminium framed guns had steel rails, I'd do it in a second.

    Along with the aircraft analogy...
     
  14. :wow: Sig Nitron coating is not just old fashioned anodizing. Gun Comes with small tube of miltec not the grease. use it first 2, 3 times and your good to go. My Sig P220C3 has never had a failure of any kind. Dirty as H#@& or not. The only reason to buy all SSTL gun is for extra weight and better second shot follow up. I Bearcoated my SSTL SIG GSR Compact's Frame only and will never need to Lube again. My BUG is my P220C3 and my Primary weapon is my Sig GSR Compact al SSTL. Reason; I can't reach the P220C3 in DA good enough to assure a win with first shot. Ideal would be to have a bug with same magazines but they SIG don't make an aluminum frame compact 1911 that I am aware of. But as caution my 1911 chamber was a min spec match chamber (O.E.M.) and would fail to go into full battery with out of spec too big reloads. So I had Bearcoat ream chamber to combat specs like my P220 chamber which is 0.0025 bigger, Now I trust it no matter how dirty chamber is and how oversize cartridge dimension is.

    You may want to do a little more research. :)

    Ever heard of the phrase "aircraft grade aluminum"? If passenger planes were made mainly out of steel they would barely get off the ground and their fuel consumption would be astronomical. Its a fact that passenger planes have more aluminum in them then steel. The entire skin of most passenger planes is made of aluminum. Heck, theres more composite material in passenger planes these days then steel. I think youre the one that needs to do more research.

    Actually, I was in the metals industry for 25 years.

    Taking your sophomoric reasoning a step further, why not advocate aluminum barrels?

    By the way, my P239 has an aluminum frame, the annodizing is wearing through to the base aluminum material.

    These Sig 10mm P220s are built on the P220ST base.

    Furthermore, as I suggested in a previous thread, do your homework on Sig Forum.

    Youre being unreasonable. And calling people names is pretty juvenile. Who would ever advocate for aluminum barrels, not me. I would never say or suggest something like that. Way to twist words there buddy.

    And the anodizing wearing off your frame has absolutely nothing to do with the type of metal your frame is made of. Anodizing eventually starts wearing off. It has nothing to do with the material that the anodizing covers. If you were in metals for 25 years you would know that.

    I guess all the gun manufacturers that use aluminum frames must be idiots. Maybe you could offer them your expertise. I mean, you were in metals for 25 years. You MUST know more than they do. :whistling:

    Yes. If you're agonizing over it this much then even if you do buy a Sig you might not shoot it that much and what's the point in having a museum piece? You may as well get something else. Pistols are made to be used. Hell, the 'rear rails' on my XDM are polymer and I don't give it a second thought, I just shoot it.

    Some people seem to be under the impression (not necessarily you) that if you can see a bit of silver under the anodizing the frame is ruined which of course is ridiculous.

    I "obsess" and have a bit of OCD when it comes to some things but I buy pistols to shoot them and they get scratched and wear, I don't clean them as often as I should, and I think they look better with use.

    Not to sound harsh, but the "analysis paralysis" isn't worth it. It's just a handgun.

    I do see what your saying. Honestly the wear doesn't bother me. I'm like you I like guns that look used. It's just worrying if a frame or locking block will fail.
