I have had mine for several years now and it will be the last inline I will ever get rid of. You can download the manual from T/C's web site and study the breakdown and loading procedures. I have all barrels except the .58 cal. Didn't think I would ever shoot it so I let it go. The .32 cal is accurate, and I really like the 12ga shotgun barrel (mine has the choke tube system). The .50 and .54 haven't been fired very many times. Cleaning is okay, you must remove the barrel from stock before you can remove breech plug, but it has not been a problem. There are a couple of System 1's for sale on either Gunbroker or Guns America that have multiple barrels (.50 & .54 I think). The balance and feel of the rifle is good for me. A conversion can still be found to use 209 primers if you so desire, but #11's and musket caps work well.
Good luck!
