Stick with the basic cartridge - Laser Ammo SureStrike Hunting Pack w/9MM Multi-Mode Catridge

Laser Ammo is probably one of the best laser products on the market for dry fire practice. I really enjoy the product. However, the Hunting Pack with the 12GA adapter is worthless in my opinion. It will not work with my Browning A5 and is lodges itself into the chamber and is very difficult to get out. I give the main product five stars, but the $35 12GA adapter has been useless for me.
