So for the last few months I've been geeking out on the Nighthawk and the HK45 but I finally managed to dig the P238 out and try it with the new "flat" recoil spring. I only had 100 rds. of Remington UMC .380 on hand and initially I was still having a couple of crushed case mouths but was able to narrow that down to one of the older generation magazines. I had a 6rd mag with one of the earlier followers, and a six and seven round magazine with the newer style followers and was only getting the crushed casings with the older mag.
The extractor shows no signs of clocking so far, but only time will tell if the gun truly runs well.
