I bought my Contender new in 1989 with a 10" 357 barrel. Still have that barrel along with a Super 14 in 223 and a couple of 22lr match barrels. Owned a few 44 mag barrels , 22 Hornet , and an original 22lr non match barrel. Never thought of parting with the Contender in the 30+ years I've owned it.I am a bit intrigued by these because of the caliber conversions. But how long does it maintain your interest as an owner?
