As for the shield`s ported barrel... you`ve been mis-led by VERY old rumors. I`ve shot my PC ported shield many times from the hip... no blast has ever hit me from the ports. As for picky ammo in the PC`s... i`ve got ported and non-ported shields, neither model has issues with ammo, at all, so long as its good american made ammo.
I realize now that many of what I read were rumors. I did read a box of JHPs at one point that specifically mentioned not to be used w/ ported barrels-- unfortunately I don't recall the brand.

Yes, it may be the heavy trigger pull that is bothering you. I don't know how heavy your trigger is but you may want to go with the APEX sear if you want a significantly lighter trigger as the PC sear alone only dropped my Shield's trigger pull to a hair over 5 lbs which is within the range of 4 1/2 to 5 1/2 lbs that I expected and wanted. This is a defensive pistol and I don't want it to go bang without intention during an emergency situation when reacting quickly. The PC sear isn't for everyone by any means. If I wanted an even lighter trigger, the APEX sear and other parts or modifying my sear face would be the way to go. The right combination of APEX sear and springs can be tailored to just about whatever trigger pull weight you might want on your pistol including A 5 lb trigger like mine. If you're not sure and want to play with things, I think that APEX is the way to go. The PC sear has a pronounced ledge on the upper face of it (likely required by S&W lawyers) which limits how low the trigger pull weight can go while the APEX sear does not have that. I didn't use the PC sear because I think it is overall any better. I used it based upon my previous experience with it. It works for me and does what I want for my pistols, but many others may need or want something different and APEX has the parts to make it every which way while S&W does not. I do suspect that the newer more rounded PC striker block may be more to my liking than the APEX striker block as I like it in my friend's PC 9 mm Shield, but perhaps it's only in my mind. In any event I can't find a PC striker block anywhere so I bought an APEX USB.
Roger that. I tried it out deactivating the sear after better understanding what you meant between OEM Vs PC sear. I don't have a complaint with that slight bump after trying it out several times.
After seeing a SPFD.MA stamp inside the frame I thought I got the MA compliant model, but sure enough it isn't. My other pistols are Sigs a DA/SA and a P320 striker. SA was marketed at a 4.4lb, the P320 as 6lb, and third-party tested (YouTube videos) at 7lbs IIRC. No complaints with those trigger pulls, so I thought mine was heavier than 6-6.5lbs. I still shoot better with the DA/SA but I've had that for years.
Thanks to your thread, I really should find a gauge to measure my actual trigger pull.

Being a carry I didn't want to mess with the trigger at all, but it's not going where I want at sub 7 yard distances. In its defense I've only shot 200 rounds so far, but plenty of dry-firing between the two sessions. It does feel heavier than my other pistols so I'll try to measure the pull before taking the next step, but that DCAEK you mentioned resolves another issue I'm having-- over-travel (also just learning about this due to this pistol) that can be contributing to muzzle jumping while dry-firing-- regardless of where on my finger, pad vs joint or anywhere in between.
Thanks for posting about the PC sear and your findings. Very useful observations.
