The tasco has been on my CZ for about 3 months and been through half a crate. The box said it would handle a .357 so I was not concerned. If you have a break on your gun it would help but I havent had an issue yet. Except the f ing 5 moa dot. Hard to get any groups at 100 yards. But at 50 I can get 2 inches. I pulled this off my Remington 597 VTR after selling it to buy this. I have sice made several mods as you see in my pics.
