Hi All!
I recently sold my P238 and bought a CM9 for my main carry gun. I'm quite happy with this so far. I followed the prep/lube threads and finally made it to the range last night. I put about 100 rounds through it. The first two mags, the slide did not lock back. If inserted an empty mag and racked the slide, it would lock, so i assumed there wasn't anything mechanically wrong. Mag 3 onward it ticked like a clock. I started with 124gr for the first ~50rds, then went back and forth between 115 and 124 for the next 50. No issues whatsoever. :86: I'm quite accurate if i take my time, but going from an SAO to a DAO trigger, my follow-up grouping is pretty poor. Practice makes perfect! New sites are definitely in my future as well...
One thing i did run into a few times, which i think is operator error, was jamming the first round against he bottom of the feed ramp while inserting a mag. I think the angle i was inserting the mag at was sliding the first round against the mag tube and pushing it down and forward. A little more caution with my mag inserts alleviated this, but you can see the tolerance between the first round in the mag and the bottom of the feed ramp is extremely tight, maybe 1-1.5mm.
The only other thing i'm struggling with is a slightly gritty trigger. I'm actually able to see what is causing this, and this being my first Kahr and first striker fired gun, i apologize if i miss some of the component names. below is a video illustrating the issue, and frankly i don't know if this is normal or not. There is a spring in the right side of the frame that appears to assist the trigger spring in actuating the cocking lobes. One end of this spring is sticking out into the frame, grinding against the bar that actuates the cocking lobes. In the video below, you can see this spring catching on the bar with an audible "tick". I apologize for the blurry moments, it's hard to focus on that area, but i think it illustrates my point.

Is this normal? Do i just need more grease in this area?
Overall i'm extremely impressed with the CM9. It's a fantastically simple, compact package, and i'm hoping it will serve me well for many years.
Thanks for reading.
