Hi I own a firearms training company that man arfcomers in AZ have attended. First I'm surprised that the LCP isn't working, we have 3 of them and with proper cleaning they have all worked for several years. I'd send it to Ruger with a demand that they get it working.
That said here is what my immediate instructors are carrying as BUGS OR EDC concealed
1. TPD Homicide Detective. J Frame with 38 +P rounds in ankle holster. Main gun in plainclothes, Glock 27 with New York trigger that is like breaking a piece of glass rod.
2. Female retired Army CID. S&W MP Compact, EDC Springfield XCs 9mm back up in a thigh holster. (I can't talk her into letting me see what holds the holster up.
3. Female retired AF Security. S&W MP Compact 40, Ruger LCP as BUG
4. Retired Army, Wells Fargo guard Glock 19 EDC, Glock 26 BUG in ankle holster.
5. ME, HKP2K 9 LEM as EDC, Shield as BUG, DB9 with the 12 buck magazine spring replacement in ankle holster.
All of us have many guns and I am experimenting with the MP CORE with red dot as a future edc but not yet.
