Thanks everyone this is a great forum. I think I'll go back and buy that gun. It is very plain and a bit short for me (LOP) but it is very tight and I've never owned a breach-loading hammer gun. If I get it I will post pic.s here tomorrow.
CParker-
Below are some photos of my Meriden. Since you are considering purchasing a Meriden, here are a few pointers. One nice thing about the Meriden shotgun is that the company stamped the barrel type (T for Twist as is the case with my shotgun) and barrel length (30 for 30" as is the case with my shotgun) above the serial number on the water table. You don't have to break the shotgun apart to see it, simply open up the action and look on the left side (where the chamber flat meets the receiver flat (i.e., "water table")). So check that number and measure the barrels to make sure they have not been cut back if that is important to you.
You can check the condition of the locks easily by removing a single screw on the left side lock. While tightly fit into the metal of the receiver and wood of the stock, I found they came off easily with a bit of care and wiggle, and went back in easier than they came off. If the seller permits, it might be a good idea to take a look at them to make sure everything is clean and in order.
The other suggestions I would make, you probably already know. Action tightness is best checked with the fore-end off the shotgun and you can use a bit of cellophane from a cigarette package. Placing the cellophane between the barrels and breach face, close the action. If you can't pull it out without tearing it, you have a tight action. My Meriden passes the test with no signs of loosening after over 600 rounds.
If you do buy the shotgun, you should use low-pressure loads. I have had great luck with the Federal 5,000psi load available exclusively from Midway.
By the way, I found the length of pull was a bit short for me as well and I did not care for the pitch, so I added a pitch spacer (Brownells) and recoil pad to my shotgun. On a two trigger shotgun, most folks will recommend a bit more length of pull so that your thumb isn't hitting your nose when you are pulling the back trigger. I managed to get a pretty good fit for me. Last time out on trap I shot a 21/25, which is about the best I can do with any shotgun.
Good luck, do let us know how it goes-
Doug
