Oldtrader3, I used Remington fmj 95 gr the first time I took the gun to range and didn't have any issues. Yesterday I was shooting RWS fmj 95 gr and S&B fmj 95 gr when I had so many fail-to-fire issues.
Btw my gun s/n is KAFxxxx and it has coated rails.
If it runs like it should with some ammo, but not with others ... that's possibly a hint.
No way to know what's going on with your particular pistol, not without being able to examine it, but light-strikes can often be caused by contaminated firing pin channels and ammunition issues.
Contaminated firing pin channels can happen when some owners/users get a little exuberant on their cleaning & lubrication practices, introducing excessive liquids to places where they can run into the firing pin channel (and from which they can't easily run back out of).
I dislike using aerosol cleaning products which can similarly force contaminants, debris, fouling & such into places ... or, introduce condensation which can become trapped (using an air compressor can sometimes create this issue).
The ammunition influence is most easily checked by using something made by one of the major American ammo manufacturers in your gun, to establish a baseline of performance and reliability (since that's what the company says they use for test-fire).
As a firearms owner, LE instructor & armorer for some different makes/models of pistols I've certainly had more than ample opportunity to experience and witness ammo-related functioning issues.
I don't like to throw stones at particular ammo companies, but consider what the big gun companies typically tell armorers in factory armorer classes about suspected ammo-related functioning issues, which is to try (and use) different ammo if problems are encountered in one or more brands/types.
It's not uncommon to hear of some foreign produced ammo to have harder primers than those used in some American ammo ... although primer quality and sensitivity may seem to be a bit variable at one time or another, especially when you get into the budget lines. Some companies advertise more sensitive primers in some of their product lines, and you can hear of some large LE/Gov bids listing such things in their specifications (along with other specifications they may desire, of course).
I know ammo prices are out-of-sight and availability is really tight right now, but there are some foreign-produced and "budget" American produced ammo lines from smaller ammo companies that I wouldn't use in my own guns even if they were given to me as a gift.
Even the big names can produce some occasional ammo lots with QC issues, and the less expensive budget lines typically cost less for good reason (less expensive components may mean things like less sensitive primers, dirtier burning propellents, no case mouth or primer pocket sealants).
I've seen a lot of the Winchester flat nose FMJ used for quals & practice in the BG380's & LCP's owned and used by our folks (and some other, older .380's, of course), and more recently the Speer 90gr GSHP. One guy has had good luck with the Hornady Critical Defense in his BG380.
If it were me, I'd try some other American offerings from the big names, and some JHP loads from them, as well, and see how they work.
) when the firing pin channel contained accumulated fouling, debris & sludge that gummed up everything.
