FWIW... I've got a Merkel 360, as well as a 1620EL and 1620C. They are all solid and very tight; break-in takes a very long time. I've also shot a 280EL (part of a 28/.410 set) quite a bit.With all these guns I shoot well (for me), but have to extend the LOP with a strap-on pad and a couple layers of thick carpet backing. Long arms and nose!

My 360 is choked M/F, and my use has been plantation... but very good flying... quail. It is light but well-balanced.

My only real quibble with my Merkels is that the Greener cross bolt that sticks out on the left side of the action when broken is very sharply pointed. Be careful when walking with it broken over your right shoulder or your earlobe will be bleeding!
