No, although 44 Mag is a great place for mags as you know.

Hamlund Tactical is a small Texas shop that is earning a good rep and is a site sponsor at 68forums.

They also have the best prices I've seen on PRI

AIM has the best price but shipping is $10 for a small quantity.

LCJ would be my last choice because he sticks to MSRP
They are 15 minutes from the manufacturing facility and get stock first.
Reportedly LCJ is the mfr's father.

They show the 5's and 10's in stock.

When buying these mags make sure that it says C Products Defense or you could be getting old C-Products mags which were problematic according to reports.

Methinks the 5's and 10's would be the best for long COALs.
Hopefully Hamlund will have them in stock shortly.
