I recently purchased a CZ P-10C. Serial # beginning with "C". The very first round I fired through the gun failed to eject properly and stovepiped. I cleared the gun and fired another 150 rounds before experiencing a failure to lock back. Besides these two malfunctions, the pistol functioned just fine and shot very, very accurately. I'm just wondering if the 2 malfunctions were due to the pistol being new and still so tight?? I usually shoot at the range 2-3 times per week and average about 350-500 rounds per session. I was using factory Blazer Brass and American Eagle 115 gr. I like the feel of the pistol enough so I bought it with the intention of working it into my EDC. However, I would like to be able to trust the pistol fully before carrying.
