I bought one of these cases from CPD. I had them make me a custom cut case (similar to their "SOPMOD" version). It was worth every penny. The laser cut foam looks very clean and professional. Turn-around time was reasonable (I cannot remember exactly, but, it was less than three weeks). There are two different types of foam available:
the 'regular' commercial-grade polyurethane foam
and
the 'weapons-grade' high density polyethylene foam...
The high density foam is really stiff and protects well. The 'military weapons cases' (with the pre-cut foam) sold by CPD come with this high density foam. The stock Pelican cases do not.
If you plan on transporting your weapons on an airline, and if you can swing the coin, get one of these cases. I flew to NH this fall and I had a carbine and a Sig P226 in the case. When I checked-in at the airport, they opened the case and one of the girls behind the counter gasped at the sight of such well protected, yet, evil-looking weapons. The TSA guys stared at it in admiration...
