I see some that are for 228/229 and then some that say 228 only, but I thought they were

the same. Maybe I'm wrong?

 

Would these fit/be compatible in a 229?

Yes, I use those Mec-Gars in my 229. No issues what so ever other then the bullets rattle a little.

Not the thread jack, but those mags are the same length as the 229 mags so they wont stick out further?

They are flush fitting

Cool i may have to pick up a few then myself. I only have 10 rounders now (in 40/375). I wonder why there are some that are 15 and others that are 13 rounders in 9mm.

 

Same w/ the .40 some are 14 some are 12 and i know the factory ones are 10.

228 and 229 9mm mags are interchangeable. M11-A1 15rd 9mm mags will not fit in 228 or 229 9mm produced so far.

Same w/ the .40 some are 14 some are 12 and i know the factory ones are 10.

 

The factory .40 S&W and .357 Sig mags for the P229 are 12 rounds. The 10-round factory mags were made for ban states.

The stock mag for 9 holds 13, and 40 holds 12. The other lengths have a Plus+2 adapter for more rounds.

 

I'm pretty sure I'm right, I haven't looked at my P229 mags in a while, maybe PizzaBob and Bry@n can correct me if I'm wrong.

Ahh ok that makes sense. So there is an extension for the 14 rounder. Got it. Thanks.

The extension was for the 229 SCT model. the capacity was 17/14 for 9mm/40 cal.

The 14 rounder is with the +2 extention. As is the 15 rounder for 9mm.

The 9mm extension bumps the capacity from 13 to 17 rounds. not 15.

 

Before the M11-A1, 228/229 9mm mags were 13 rounds. The only 15 rounders were after market mags. Mecgar makes a 15 rounder for the 228/229 9mm that fits flush. The difference is in the follower.

 

The M11-A1 actually increased the internal dimension of the grip to that of the 40/357, so the 9mm mag has a 15rd capacity but it will not fit in 9mm 229 or 228.

Some gold info in this thread. It should also be noted that Mecgar made the mags for Sig, so I really don't feel like they are after market.

Mecgar makes mags for a lot of guns, but to their spec.

 

The 15 rounders are the Mecgar branded mags, not the OEM ones that comes with the 228/229 when you buy them. Before the M11-A1, there were never any flush fit Sig branded mags for the 228/229 9mm greater than 13 rounds.

there's actually 2 types of P229 mags for 9mm

the old ones are 10, 13, 15 rounds.

the new p229 are p229-1 E2 10, 15 rounds.

the new mags won't fit the old guns.

the old mags seem to fit the new guns but I don't really know if it'll really cycle.
