Both our Heavy and Light Tree's are suitable for handgun calibers. The (lite) 1/4" AR500 tree is a little better suited for smaller handgun calibers. The plates swing more reliably with a single hit on these thinner plates. On our (heavy) 3/8" AR550 tree, this works well with all handgun calibers including magnums. (on the smaller calibers, they may not always swing the plates with a single hit) We also have a lot of customers who use these with center fire rifles with great results! (The plates hold up great!)
