Well for many of the mods you will likely want to start with a newer 1322.Yes it is true that there is no provision for the bolt to pull back the hammer on that older 1322, and as such you will still have the use the nob to cock it separately even with the steel breech.Though with a new 1322 for $55, and a steel breech for $40 (after shipping), then an additional $25 in materials and parts you can have one very powerful 1322. Add another $25 if you want the 1399 stock.
