Yea Swizzle. D/A = Dual Action.

Best of both worlds: scale release, clip release, button, bolster release, hidden release, and many others.

I kinda want one of the D/A SOCOMs, but they're nothing special. Their rocker bar lock is thinner and it's a simple button auto (which makes it illegal).

The LCCs are pretty cool but rare to find in plain edge with a decent looking style blade. Bolster release is very well done on the LCC.
