Tony spoke with me also, about his experience with the Executives Companion, as I'd been using one for years, and wondered about the EC vs. VM2 thing.
I'm currently using VM2's for my Colts' Commander, G19, S&W 2.5" 686/4" 66 and 3" 65.
And an Executive Companion for the big fatty Glocks (ala G20 and 21). Non mas fina for the big Glocks, IMO! That paddle makes a huge difference. And an Executive Companion for the G34.
If I had to make a choice, as to which is more concealable or more comfortable, I'd have a really hard time choosing.
I've currently an elephant Axiom and another horse/shark VM2 on order......
You'll be happy with any of 'em. Toss a coin.
