Heck, I'll even make it more confusing.
CS45 mags also work in Star M45's.
Which also means I use Star mags in my
CS45, just like the 45xx mags.
Makes range day pretty easy with them,
with 10 interchangeable mags
The Star's barrel is a half inch longer,
due to the controls being in the frame.
Which also make it a hair more precise,
as per my previous comparison post
last year
Star also used the S&W 59xx mags in it's
Firestar Plus M243 9mm, Model 28, 30, & 31,
and seems to have used other S&W mags for
standards in its other "Number" model productions.
Keltec also seems to have that bad 59xx habit,
with the P11 & Sub-2000 using them,
along with the Springfield XD compact &
the Marlin Camp 9
It's truly amazing what magazine compatibility
exists in the gun world!!
