I thought the difference was the trap door in the back for clean patches/smokes.

Out of curiosity, whats the difference between an A1 and A2 stock?
the A1 buttstock was made of a hard blackplastic if i remember right the name of it was called bakelight but i could be wrong on the name of the plastic. the A2 was a more advanced material that absorbed shock better when use the weapon in hand to hand combat. both A1 and A2 have trap door storage areas. dimensionally they are the same the only difference being what hte stock itself was made of. the A1 material gives it a very cheap shiny black feel which, the A1 stocks feel like something you would expect to find on a child's toy.
I think that the A1 stocks are a bit shorter than the A2 versions.
I have an 1980's vintage Colt SP-1. I still have the triangular handguards (in storage), but I replaced the original pistol grip (it was to small for my ham sized grip) and I added a butt stock extension to get a longer length of pull.
Unfortuantely, I have misplaced the original pistol grip and butt stock end plate. I'll need to replace these eventually to return the rifle to its original condition when it gets retired to be a gun-safe queen.
