My club is shooting more 2-gun and 3-gun matches. Unfortunately, my only shotgun is a Mossberg 835 with a 5-shot mag. What does everyone recommend for a "reasonably" inexpensive shotgun to fill the void until I can scratch up enough money for the Winchester Super X2 Practical? I have been looking at inexpensive pumps like the Winchester 1300, Remington 870, and Mossberg 590. Any experience/preference between these shotguns? I have heard a lot of positives about the Winchester 1300, but Remington's 870 seems better supported in the aftermarket accessory business.
