I squirrel hunt with a laminated Remington 870....a synthetic Remington 1100 LT-20.....and a synthetic Beretta 390.....all are 20 gauge. I am thinning out my collection to make some room in the safe....but I can't decide on which ones to send down the road and which one to keep. I think the safe bet for future parts availability is the 870....which concerns me on the 1100 and especially the 390. All these guns are in mint condition with low round count. The 870 and 1100 are similar in weight .....the 390 seems noticeably heavier to tote around in the woods. Opinions?
