I picked up a null for suit wear - my tailor said it was easier to conceal a gun there, than in the pockets - his suggestion is to carry things in your jacket, and not use pant pockets in suits.
Hopefully, Alessi has things going better - they made a holster for me, but missed their delivery date by quite a bit.
(The longer I've been in manufacturing, the lower the tolerance I have for the "fuzzy" delivery dates in the gun industry. )
