OK same overall subject- I've a nifty SIG P938 that I've been carrying, as it's very svelte and easily disappears. I haven't carried my pet PMF SC build yet. It is a fat little sucker in comparison to the SIG, but with a flannel shirt worn untucked, shouldn't be much more difficult to keep out of view.
The SIG is OEM. I may (or may not) upgrade the sear spring and mainspring housing to the OEM V2 versions (there were issues with V1) as mine was made in 2014 before the change, and am considering changing the hammer spring & firing pin spring to the MCARBO kit. I'm not going to replace the shoe with an aftermkt unit. If SIG finally offers the LEGION trigger shoe alacarte, then I might.
My PMF SC does NOT have a std Glock trigger per se', but DOES have all Glock OEM triggerwork aside from the RangerProof shoe itself. The frame is NOT serialized. Down here in So OR, I don't think that's a big issue, but I may hunt-down the instructions here on the forumfor etching your own # just for grins. I dunno.
I'm looking at the S&W CSX as a factory alternative for a high-capacity micro-9mm carry, as I think it's less bulky than my SC, and is FACTORY issue. I've read reports about its trigger- some hate it, some say it's great. My salesperson at one of our LGS' here when I asked them if they had one in stock "no" was the answer but said they could get it literally overnight, and they said it was their own carry weapon of choice. I asked about the trigger on theirs- theirs was very, VERY good, and overall it's been their favorite EDC unit to date. Go figure.
I could also carry my Echelon (need a holster for it) but that sucker is full-size and being a double-stack unit, wider than a 1911. I'm not sure that's the right carry choice for my build, though. I could probably carry an officer's or Commander comfortably concealed. Point being, I'm not a walking tree-trunk. lol. Also uncomfortable about carrying with a loaded weapon pointing at certain bits, ie appendix carry. Right now, I feel most comfortable with OWB, on the hip, concealed.
