FAS/Domino SP602 and its replacement SP607 are first rate 25 Meter
ISSF Standard Pistols/Sport Pistol.
Keep them clean (and I mean clean, strip clean every match, every
practice), oil the magazine follower and they will operate pretty
much without malfunctions. They are simple to strip and clean, no
tools required.
The two weak parts in the gun are the new recoil springs and the
firing pin. The recoil springs they sell now only last 1/2 year (they
lose their compressive nature, it isn't a funciton of #rounds fired).
The firing pin, well, that just a bad design.
If you cannot get parts from Guns N Things in Alberta, you can
contact FAS via e-mail to obtain parts
info@fasdomino.com.
I think, not 100% sure, but the SP607 mags will fit the SP602.
It is part #118 for the magazine.
