Q Research Gun Review
The Ithaca 37 is a pump-action shotgun made in large numbers for the civilian, military, and police markets. It utilizes a novel combination ejection/loading port on the bottom of the gun which leaves the sides closed to the elements. Since shotshells load and eject from the bottom, operation of the gun is equally convenient for both right and left hand shooters. This makes the gun popular with left-handed shooters. The model 37 is considered one of the most durable and reliable shotguns ever produced.
In the case of the Ithaca Model 37 shotgun, if you hold the trigger down while you continue to rack the weapon, it will fire without you having to let go of the trigger.
