Solid w/ Geissele Super Stabby mount.
I had not had my hands on one since basic training over 33 years ago and it brought a host of memories flooding back to me. The weight, the balance, the fine edge of....."cold steel." It's going to fit perfectly on my 590A1, when I get it and I plan on purchasing a backup.
This knife was purchased to replace a knife that was stolen, with other hunting gear, at the cabin. The stolen knife was one that was carried during multiple tours in Iraq and Afghanistan. The new knife is a worthy replacement. It is heavy, strong, and quality made in the U.S.A.
