One of the best O/U built, I've had five over the years. Only had a problem with one, a chipped firing pin tip while shooting shells made in Taiwan(I was shooting in a tournament there). They have mechanical triggers so even if your shooting very light loads that wouldn't set an inertia trigger they will work in a 101. One of my 101 I've been shooting since 1966 and has well over 100,000 shells through it and still is tight as a drum. Non of mine were built with steel shot in mind(all pre 1968) and have pretty thin barrels. I have quite a few shot guns but if there is money on the line out comes the 101.
