M1 Carbine Magazines. What’s Good?

So, I just picked up a Fulton Match Carbine here in the BX from M21Fan and it’s a real beauty! And I’d like to get some 15-30rd mags for it, but Geez Louise! Prices & options are all over the place, one would think to get the USGI but those are a lot pricey and not easily found, commercial aftermarket are less than half the price but quality seems to be a problem, some purportedly work, some don’t, some will hold the bolt open, some don’t, some folks say ProMag is the best, KCI is good, most everyone believes Kahr is junk…Then there’s the 30 rounders, USGI 30’s are cheap, but you need either an M2 trigger housing or M2 mag catch to use those? But the commercial 30’s will usually fit the M1-M2? From what I gather magazines have always been the Achilles heal for the M1 Carbine.

I have 6 of the Hardback 30 rounders, two of which work fine. The other four are still sealed in original package. Most other 15 round are USGI issue and some still in wrappers, all work fine in my two 1944 Underwood carbines, Kahr arms and Iver Johnson rifles. Also have several of the Korean made magazines of which I have used two with no problems.
Did try a 5 round hunting magazine with failed miserably. Awhile back Midway had some good offers on USGI magazines of many different manufactures, all the ones I ordered were in great condition or still wrapped, bought the Underwood branded ones only. Went with the grade 1 when purchased.
Pouch and mags was $230, one split back and 3 hard back, all have bolt hold opens followers.

Fifty bucks apiece :rolleyes:. I got the KCI (Korean) 15 & 30’s for something like $15 each, they look exactly like the Korean surplus mags with a hold open follower :unsure:. Just wish time & weather would cooperate to try them with the Prvi ammo as my range tends to flood in these daily monsoons :cry:. Summer is over soon and looking forward to Fall with cooler & dryer temps.

Tried your M-1 Carbine magazines out yet Cool Breeze?

I want to get to the shooting range with relatives. They need a refresh on using firearms. Now I also live in Florida.

Not yet, the weather has been oppressive lately, rainstorms everyday, thick humidity and triple-digit heat index, my outdoor range also tends to flood this time of year. I’m waiting on cooler Fall temps, and I’m itching to try that carbine and a few other rifles & pistols I’ve been working on this Summer. I’m North of Tampa and use the Dade City range, $25 gets you in all day.

I do not know if you got a chance to try your new M-1 Carbine magazines yet Cool Breeze, but I went out to an outdoor shooting range recently. Mostly shot .22 Long Rifle out of a Mossberg model 702.

But I also did some fine tuning on a 7.62 x 39 AR-15. With Russian Igman brass ammunition, I zeroed the rifle to 100 yards. All twenty-five shots worked great and I practiced tactical reloads.

The front rail came loose though on the rifle. I tightened the bolts back up and tried to glue it on with Locktite. Hopefully it will not come loose again.

Several years ago when I was a member of the old Battlerifles Forum I bought ten KCI M1 Carbine mags from a forum member. I had five carbines at that time. The KCI mags wouldn't fit in three of my carbines and would reluctantly fit in the other two carbines.

I contacted the seller and he made it right by sending me a few hundred rounds of reloadable brass cased 7.62x39 S&B ammo. I still have the KCI's somewhere in my storage unit.....................

On the other hand I have a few dozen USGI 15 round mags that work great.

Okay, I'll post it again at the risk of whatshisname jumping all over me again - That's impossible. How do you know? Are you an expert? Did Granddad steal it from an armory in 43? Did you remove the bayonet lug? Did you swap the newer sights for the old type?... And so on.

Nice carbine. And yes there are a bunch of carbines that did not go through the post war refurbishment where the adjustable rear sight and bayonet lug were added. They are still in the original early configuration with a type one rear sight and type 1 barrel band. Don't let anyone tell you different. There are a lot carbines that have been restored back to original and if done correctly it can be hard to tell. So who knows.

Well, I will say that some folks will 'restore' a carbine by installing correct parts. However without provenance there's really no way to tell if the firearm is original or restored.

A lot of money can be spent making a firearm correct in parts but not in fact. They are only correct when they leave the factory, otherwise who knows?

Buy the gun not the story unless there's a paper trail.

I know a place that will restore military weapons. They have an unreal number of boxes of original parts and original tools. The do different shades of parkerizing and stock finishes. When they finish with it it looks like it just left the factory.

A lot of Carbines and Garands have been redone for various reasons. A lot of weapons were pieced together in the 60's and 70's by various companies using the huge amounts of surplus parts that were available and cheap at the time.

There are weapons out there that did not go through post war refurbishment.

If you like it buy it. Just know what you are buying. Pay a price that is on par with what you are buying. As in many things knowledge about what you are buying is important.
