Update: It is still hit and miss on emptying a full magazine of live rounds by racking the slide by hand. Sometimes I can empty be it with no issues and the next time it jams every time. Again this is not acceptable because what if, during an altercation, God forbid, and you need to clear a bad round? Here's the wording my most recent email to Erica at Ruger CS:
Hi Erica,
The replacement slide and barrel assembly arrived. Unfortunately, it's acting the same as the original slide that mine came with before I modified it. I'm not sure if you are familiar with any Ruger forums online with owners complaining of the same issue. There are many LCP Max owners that have received replacement slides like I did and are giving up on the LCP Max because of this. We do not understand why some Ruger CS reps are telling us that this is normal. This is definitely a defect. Yes, not everyone is experiencing it but many are. I know that it has something to do with the "cartridge recess cut" because removing it helped mine. I've looked at other demo pistols at different gun stores and noticed that not all "cartridge recess cuts" look the same. Are some are cut better than others? Your engineers need to figure something out to remedy this. I will continue using my modified slide because with the "cartridge recess cut" removed, it seems, for me at least, to have fixed the issue. Ejection is not weak or erratic. Spent shells fly 6 feet away and land at my 9 o'clock to 6 o'clock position. And I've never experienced any hitting my face. I knew that there was an issue with ejecting live rounds by racking the slide by hand because, even with a much heavier recoil spring, my Glock 27 Gen 2.5 ejects live rounds fine by racking the slide by hand every time. Can't say that with an LCP Max with a "cartridge recess cut.". Thanks for your time.
