Thanks 92FS for the plug.
I'd call the trusight an advanced gun over the Edge - for three reasons.
1. Lighter - driving the gun from target to target is quicker (less mass = easier to start and stop) and less recriprocating mass (the slide) tends to have less felt recoil.
2. Sight on the barrel. It tracks easier since it is moving a lot less, lets you stay on target for the follow up shot.
3. Expansion chamber. With regular loads, it doesn't do a lot, but if you play with reloads in slower powders (like 4756 or HS-6), it actually does keep the gun flatter.
To the newer shooter, they're going to find the Edge easier to shoot. It's sheer mass in the slide and frame keep recoil down, and they don't notice the target to target movement being a little slower. To a more experienced shooter, the trusight will be better out of the box.
If I was taking one out of inventory, I'd be shooting a trusight now. (but my IPSC Commemorative is just too pretty)
You won't be disappointed with either gun.
