I currently have two. A 12 gauge Pigeon (28 barrels with a vent rib) and a Heavy Duck (30 barrels with a solid rib). I use them for traveling guns when I am uncomfortable taking some of my other guns; for inclement weather; or, hunting the salt marsh. One of my sons shoots the Pigeon a good bit around home. Between the two of us, they have had a good number of shells put through them.
Before I bought the Heavy Duck, I shot the Pigeon for about 10 years. I have been shooting the Heavy Duck for the past 4 years or so. When I bought the Pigeon, I sent it to Mike Orlen and had the chokes opened to IC and Mod. The Heavy Duck was Mod and Imp Mod when I got it. Both guns have digested a lot of 3 Challenger steel loads in Canada, a variety of stiff duck loads at home, and have been used extensively for doves and snipe. I occasionally shoot sporting clays with both.
Never had any trigger issues. Similar to Cold Iron, the only mechanical issues I recall dealt with the fore end and keeping the latch screws tight. If the screw(s) were not tight, I had ejector issues. I found lock- tite solved the issue for me. I did manage to break the stock once and Midwest Gun Works sold me are replacement. I also bought a parts kit of replacement parts from them. It fits in a small tin box and travels in my shell box. Never needed any of the parts from the kit, but it is a comfort having it at hand.
They are not lightweight guns, but I am fine with that. Other than double triggers and getting rid of the vent rib on the Pigeon, the only thing I would change is the sharp corners on the bottom of the receiver. Rounded off edges would be more comfortable for carrying the gun. It would be nice if I could find/make a splinter fore end and have choice between that and the beavertail.
All in all, the guns have proved to be good mid-level guns which have stood up to hard use.
