My mini is fairly old (bought it used) and lately ive been wondering if i shold replace the spring, firing pin, bolt and other parts that have been subject to wear.

opinions?

If it ain't broke. Don't fix it. Its an old saying but its true. The mini will last a long time. If you've fired 10,000 rds or so, then it wouldn't hurt to check chambers head space. One of my projects is to build up a spare parts kit for my mini, like springs, firing pin just so I will have spares. Here is a place to get some extra parts if ya want, but not much seems to break on the mini.

broken in - those will be your most reliable parts! Just keep a spare firing pin, hammer spring, and maybe a recoil spring around.
