I have three a Z2 M2 converted to LED and a M3. My choice would be the Z2. It's smaller really bright and is what the FBI uses. My second choice would be the M2 with standard bulb Assy. It has a shock absorbing bulb holder.
I'd go with either the A2 out of that bunch, or better yet, the L2. The L2 is LED, has two stages, and is digital. You will love the white light it puts out. If not, the A2 at least gives you some LED and then the incandescent burst you want.
The Luxeon Star LED's are way more durable than a incandescent bulb.
Just take a look at the X200's for handgun mounting, that is one bad light! And I mean that in the best way! The X200 is what I have been looking for, for a LONG time.
