Sig P220 Mag problem

[Promod1385]

I ordered 2 new "promag" 10rd mags for my P220, I loaded 3 rounds into one of the mags last night, I inserted the mag and dropped the slide, it chambered a round no problem. When i rack the slide it will eject the chambered round but will not pick up the next round from the mag.

What causes this problem? Does the mag just need to be shot a bit and broken in? Is this a tuning or set up issue?

Did the other mag work? Maybe a mag spring issue?

There is a simple cure for your problem. Take the pistol and hit the mag release. Let the mag drop free. It doesn't matter if it hits the floor. Better yet, let it hit the floor. Then pick it up, making sure that it's free of ammo, and whack it with a sledge hammer, flattening it, and throw it in the garbage. Then, go order some factory mags.

Yep the other mag seems to work fine.

It seems the problem mag is a bit tight as I can not simply pull the slide back with an empty mag and have it return to battery. I must use the mag release and pull back on the slide.

Actually Storm was giving you good advice; PROMAGS SUCK.

 

[rellascout]

Remove Promag from the gun. Place mag in trash. Order A few Act/Novaks from GregCoteLLC.com Sig P220 8 round .45 ACP blued $19.95

Problem soved

In all serious Promags are really bad mags. Most of time its bad springs not followers. If you must keep them get a new set of springs.

Tommygun, obviously you read my previous posts. You really have that little self control? "if you don't have anything nice to say, don't say anything at all".


Actually i take that back, I do appreciate your opinion (i think everyone's opinion has some value in our society).

Remember "its not what you say but how you say it" learn this and use it! Until then you can both take your caustic and rude tone elsewhere.

Been There Done That

ProMag makes some decent Mags ,but not in the application you attempted.
Suggestion:
I run 45ACP 220s in USPSA & IDPA. I have found ACT-MAGs
and Sig Mags are "To Hell and Back Reliable" in my Guns.
( I think ACT-MAG makes the Sig Mag )

Promod, I tried to give you very good advice with a touch of humor. Oh well.

I stand by what I said.

Promags are generally not quality products. The company does produce a few models that are good (M1 Carbine comes to mind), but most are problematic. If you do an internet search, you will find a compelling number of accounts of problems with Promag products.

Magazines are at the heart of the reliable operation of a semi-automatic pistol. Your Sig P220 is a high quality pistol; do yourself a favor and spend a few extra dollars to get high quality magazines.

I'll try this from a moderator's point to avoid unneeded conflict between members.

If you're going to ask for the cause, sometimes you have to be ready to handle the answers. In this case the answers you are getting are not what you expected...but they happen to be correct. The suggestion to throw them away or destroy them is constructive advice. The rule of thumb about magazines is that when they start to malfunction...throw them away. It is like brake shoes on a car. they are a consumable item.

ProMag generally makes sub-standard magazines. Their major value is their use for clearance/malfunction drill practice, because they can't be counted on to feed reliably. If you have one that is functioning, it is the exception to the rule. Why would you even buy ProMags to use in a Sig 220 in the first place?

I actually have 4 ProMags for my Sig 220. I got them from a student at a class who couldn't get them to even run through a string of fire. I hand them to students to use to see how they will handle a jam.

I have 6 Sig Stainless mags, 6 dovetail-back ones and 25 Act Mags which funtion flawlessly

220 10 RDN Mags

I have 2 or 3 10 RND mags for my 220 that I will part with If you are interested. Work fine but I do not use them anymore. I just looked for them and found 1 no markings on it.

I have the P220 with FACTORY mags and several were catching. If the grip panel screws are a tad too long, they will catch on the side of the magazine and cause a tiny scratch, the magazine won't eject properly because it is wedged in there by the overly-long four grip screws.

I would not drop any magazine on the floor. Good way to bend the ears and have real problems!

If the mags don't work with your gun, send them back and see if you can get some good used magazines for that gun.:banghead: Beware, those magazines have weld spots down the back where the magazine is folded and then welded together where the metal is kind of cut like a zipper. I bought a bunch of used OEM mags that I disassembled then found that there were tiny separations at the top of the back - apparently due to the pressure of the loaded magazine and top cartridges acting like a wedge, trying to separate the magazine lips. A friend spot-welded them in a number of locations and then I filed down the welds and blued them. Now the mags are as good as new (or better)!

I plan on using the gun to shoot IPSC Limited 10 thats why i wanted to try some bigger mags.

The followers are different on my factory mags they have a small nub at the rear of the flat portion of the follower. I am assuming this holds the round at a more desirable angle for the gun to pick it up.

I also noticed the cut at the back of my stock mags is very smooth and round, the promag piece is not. I am not a manufacturing engineer but it appears they were stamped in a different order during manufacture and this why the shape is slightly off.

My cousin who is a machinist/fabricator is advocating clamping the promag in his drill press and correcting the cut in the rear of the mag, he also wants to put a small spot of tig weld on the follower and file it to match the factory follower I have.

I have a call in to Promag (tech is out today, will supposed to get back from me on Tuesday) it really chaps arse that they advertise all of this "quality" crap on there website and create such an imperfect product. If they give me the go ahead to try correcting the mags without voiding my ability to return the mags i will give it a try, if not i will return them to the retailer i bought them from and get my money back.

Why bother...? do a search and you will find out that Promags suck. People here have told you the truth and given you sound advice. I can tell you right now that if you modify the mags the retailer you bought them from will not take them back.

If you are shooting competition with the gun please do yourself a favor and get a Sig factory 10 rounder...

Top gun normally has them for $35... but they are out of stock right now. You own a $600+ gun why try to run cheapo mags in it?

 

[docnyt]

I don't run Promags in my P220. I use SIG, ACT and Mecgar in my SIGs. The one Promag I tried in an RIA 1911 double stack will not eject. Granted it was designed for a Para P14 but they are supposed to interchange.

Anyway, if you swap out the spring and cannot get it to feed reliably, I would just return it or discard it, especially if you plan to use it in competition.

I second the GregCote recommendation. I bought some Mecgars from them with excellent communication and fast shipping.

 

[Promod1385]

Well Promag might have a poopy product but they do have good customer service to back it up!

There tech just called me back, explained that they have done a re-design on these mags and have new ones in stock. He is sending me a return authorization and 2 of the new design mags. He said they changed the follower angle as well as the feed lips to cure these problems.

I will give the new ones a try and if they don't work i will get my money back.

Who are you going to get your money back from? The retailer is not going to give it back to you. You are not returning the product you bought from them. Again why not simply cut bait return the mags and get ones that will work? New cheap redesigned crappy mags are still just crappy mags. What did you pay for the promags?

I am not surprised to hear of your problem, as I too have had poor luck with this brand. If you got one that worked, great. You may be able to get a refund or replacement on the other. I would still not use even the "good" one for defensive carry, but it is OK for range practice to save wear and tear on your factory mags. I make a policy myself of only using magazines from the maker of the gun, with the exception of Mec-Gar, who is an OEM for several brands, including SIGs.
