3906 mag in a 3913?

[scwv67]

I know the mags from a 5906 can be used in a 6906 with some type of adapter, so I was wondering if a 3906 mag would work in a 3913.

In addition, are 3906 mags unobtanium? Am I correct in doubting there's a similar type of adapter ala 5906 to 6906? Finally, am I correct in that if such swap is possible, I would only net one additional round?

Thanks.

You can still get 3913 mags curved or straight bottom also 3906 mags from S&W. 3906 mags as well as 39 to 639 mags will work, I've never looked for an adapter because I really don't care. I have seen used 3913 mags going for stupid prices on flea bay which makes no sense when you can buy new most of the time for less dollars.

I have a 3913 and a 3904. If you use a 9 round 3904 in a 3913 they work fine and give you a little more to hang onto on the bottom and one more round. I don't know of any sleeve for the magazine and I do not think one is needed.

I also have a 5906 and a 6906. I often use a the 15 round 5906 mag in the 6906. I do this in IDPA and I slam them in and since they are tapered at the top there is no problem. I have never used a sleeve for these either.

Midway usually has a good selection of S&W mags and they often have sales.

This has come up before. Yes, the 3904/6 magazine will fit in the 3913/14/53/54 and work fine.

There are both 8 round and 9 round OEM magazines for the 3904. Most of mine are 9 round, but I think I have one 8 round as well. Same size, so it's probably possible to convert an 8 round into a 9 round. OR ruin it trying. Maybe some day I'll take one of each apart and see.

Sorry for the noob question, but thanks to everyone for their input!

Looks like 3906 magazines are available from the S&W store. Not cheap, but available.
