I have a CW380. Second owner- though it was pretty new when I got it. Prev owner not shot it much.
I broke it in and have placed maybe 300-500 rounds through it (maybe more). Reliable. Love it. EDC is great.
But.... not long ago when cleaning, I noticed circular cracks in the polymer at the back end of the front rails (just above the finger spot in the trigger area).
See this pic (top view- slide removed)-to show the general area where this is happening (yellow arrows). You can't see it from on top- only from on end view. As best I can tell, the "lug" on the front end of the slide- that seats the main springs.. when the gun is fired, that metal comes back and hits this area before moving forward and returning to battery.
Hard to photograph.... but this is what's happening and concerns me (see below).
You can see a significant curved crack on the right side of photo (yellow arrows).
You can also see where a similar piece broke off on the left side of this photo (red arrows).
So when I say in the title the "frame" is cracking.... this is what I mean.
One of my concerns is: if this area continues to deteriorate, will those guide rails eventually come loose?
Is this not a big deal?..... or potentially catastrophic? I'm obviously extra concerned since I am not the original purchaser.
Has anyone else seen this? Is it happening on your gun?
