Yep, the K100 is one of those guns you need to try for yourself.
The trigger is way lighter in single action than you would expect.
The single action reset is unusually short.
The felt recoil is unusually mild for a polymer framed 9mm.
The rotary locking barrel is very smooth in operation.
I have been using them since 2007 and am waiting on my third (and possibly fourth and fifth)
(GP K100 Mk5, STI GP6, GP X-Calibur, GP K100 Target, and K22 X-Trim)
So has anyone in the US with a recent Century Arms import checked the magazines? Are they actually 15 rounds, or do they really hold more? The guns used to have a 17 round magazine.
