I have decided I want to get a semi auto 12ga. I grew up hunting whitewing but have not hunted much else birdwise, plan on waterfowl, upland, geese and turkey. I have a handful of shotguns but no semi autos. Was planning on trading in my 870 Magnum for a semi auto, preferrably a Remington 1100/1187since I have all the chokes including a TruGlo turkey choke, but doesn't have to be. Any suggestions on a decent, reliable, not too pricey semi? I kow I can get a smoking deal on an older gun at my local shop (got my buddy a nice Browning Lite 12 for $300) but many older ones are 2 3/4" only and some do not take choke tubes. Like to keep it under $500 and have no problem with used.
